FOSS Circuit Simulators

AN OPEN-SOURCE, FREE CIRCUIT SIMULATOR
by: Bryan Cockfield on July 30, 2023

The original circuit simulation software, called the Simulation Program with Integrated Circuit Emphasis, or SPICE as it is more commonly known, was originally developed at the University of Califorina Berkeley in the 1970s with an open-source license. That’s the reason for the vast versions of SPICE available now decades after the original was released, not all of which are as open or free as we might like [1].

Fig: The Quite Universal Circuit Simulator includes a GUI based on the Qt toolkit and handles ad and ac analysis, S-parameters, harmonic balance analysis, noise analysis, and so forth. 

We’ve [2] listed all the simulators we found - the good, the bad, and the ugly - that actually did perform circuit simulation in some fashion. They are provided alphabetically, along with the most notable benefits and drawbacks we uncovered.

Anstract: The electron fluid model in plasmonic field effect transistor (FET) operation is related to the behavior of a radio-frequency (RF) cavity. This new understanding led to finding the relationships between physical device parameters and equivalent circuit components in traditional parallel resistor, inductor, and capacitor (RLC) and transmission models for cavity structures. Verification of these models is performed using PSpice to simulate the frequency dependent.

Abstract: This work highlights the utilization of the floating body effect and charge-trapping/de-trapping phenomenon of a Silicon-nanowire (Si-nanowire) charge-trapping memory for an artificial synapse of neuromorphic computing application. Charge trapping/de-trapping in the nitride layer characterizes the long-term potentiation (LTP)/depression (LTD). The accumulation of holes in the potential well achieves short-term potentiation (STP) and controls the transition from STP to LTP. Also, the transition from STP to LTP is analyzed through gate length scaling and high-κ material (Al2O3) for blocking oxide. Furthermore, the conductance values of the device are utilized for system-level simulation. System-level hardware parameters of a convolutional neural network (CNN) for inference applications are evaluated and compared to a static random-access memory (SRAM) device and charge-trapping memory. The results confirm that the Si-nanowire transistor with better gate controllability has a high retention time for LTP states, consumes low power, and archives better accuracy (91.27%). These results make the device suitable for low-power neuromorphic applications.

Abstract: A physics-based analytical DC compact model for double and single gate TMD FETs is presented. The model is developed by calculating the charge density inside the 2D layer which is expressed in terms of the Lambert W function that recently has become the standard in SPICE simulators. The current is then calculated in terms of the charge densities at the drain and source ends of the channel. We validate our model against measurement data for different device structures. A superlinear current increase above certain gate voltage has been observed in some MoS2 FET devices, where we present a new mobility model to account for the observed phenomena. Despite the simplicity of the model, it shows very good agreement with the experimental data.

DOI: 10.1038/s41378-023-00565-5

Abstract: Organic electronics can be biocompatible and conformable, enhancing the ability to interface with tissue. However, the limitations of speed and integration have, thus far, necessitated reliance on silicon-based technologies for advanced processing, data transmission and device powering. Here we create a stand-alone, conformable, fully organic bioelectronic device capable of realizing these functions. This device, vertical internal ion-gated organic electrochemical transistor (vIGT), is based on a transistor architecture that incorporates a vertical channel and a miniaturized hydration access conduit to enable megahertz-signal-range operation within densely packed integrated arrays in the absence of crosstalk. These transistors demonstrated long-term stability in physiologic media, and were used to generate high-performance integrated circuits. We leveraged the high-speed and low-voltage operation of vertical internal ion-gated organic electrochemical transistors to develop alternating-current-powered conformable circuitry to acquire and wirelessly communicate signals. The resultant stand-alone device was implanted in freely moving rodents to acquire, process and transmit neurophysiologic brain signals. Such fully organic devices have the potential to expand the utility and accessibility of bioelectronics to a wide range of clinical and societal applications.

[chapter] GAA Transistors

Challenges and future scope of gate-all-around (GAA) transistors

Introduction: No doubt, FinFET technology is the slogger of today's semiconductor world. But as demand for further scaling with a desire for ultra-low-power and high-speed applications results in undesired short-channel effects, a new transistor is required. This is where gate-all-around (GAA) devices come into being. The GAA structure helps to mitigate unwanted short-channel effects by enhancing channel controllability. In GAAFETS, the channel surrounds all of its sides through a high-K and interfacial oxide layer. Thanks to science and technological innovation, the GAAFET family brings together different transistors and their competitive benefits. This chapter tries to answer why and how 3D devices emerge. In addition to the limitation of FinFET (a 3D device, gate surrounded by three sides), it further talks about the scope and challenges of different competitive GAAFET members (nanowire FET, nanosheet FET, junctionless nanosheet FET, complementary PET, and forksheet FET) of the GAAFET family. It is worth mentioning that a smaller benefit of the device performance exerts a massive performance enhancement on circuit-level applications. However, the advantages of device enhancement concurrently exaggerate the limitation of devices at circuit-level applications. So, an elaborated idea of GAAFETs holding the benefits and challenges at the circuit is also discussed here.

Abstract: A non-quasi-static compact model well suited for the simulation of the electrical behavior of printed organic thin-film transistors (OTFTs) is proposed and validated. The model is based on the discretization of the current continuity equation by using a spline collocation approach, while the electrical transport in the organic semiconductor is described by the variable range hopping theory. The model accounts for the presence of parasitic regions that are often found in the layouts of printed OTFTs due to large process tolerances. The model has been implemented in the Verilog-A language and has been validated by a comparison with the capacitance vs. voltage (small signal) characteristics of the devices and measurements made on OTFT-based common-source amplifiers (large signal). A comparison with a quasi-static version of the model is reported.

Description: 75th Anniversary of the Transistor is a commemorative anniversary volume to celebrate the invention of the transistor. The anniversary volume was conceived by the IEEE Electron Devices Society (EDS) to provide comprehensive yet compact coverage of the historical perspectives underlying the invention of the transistor and its subsequent evolution into a multitude of integration and manufacturing technologies and applications.

The book reflects the transistor’s development since inception to the current state of the art that continues to enable scaling to very large-scale integrated circuits of higher functionality and speed. The stages in this evolution covered are in chronological order to reflect historical developments.

Narratives and experiences are provided by a select number of venerated industry and academic leaders, and retired veterans, of the semiconductor industry. 75th Anniversary of the Transistor highlights:
  • Historical perspectives of the state-of-the-art pre-solid-state-transistor world (pre-1947) leading to the invention of the transistor
  • Invention of the bipolar junction transistor (BJT) and analytical formulations by Shockley (1948) and their impact on the semiconductor industry
  • Large scale integration, Moore’s Law (1965) and transistor scaling (1974), and MOS/LSI, including flash memories — SRAMs, DRAMs (1963), and the Toshiba NAND flash memory (1989)
  • Image sensors (1986), including charge-coupled devices, and related microsensor applications
With comprehensive yet succinct and accessible coverage of one of the cornerstones of modern technology, 75th Anniversary of the Transistor is an essential reference for engineers, researchers, and undergraduate students looking for historical perspective from leaders in the field.
