[ESSCIRC 2015] Low-power analog RF circuit design based on the inversion coefficient

[ref] Enz, Christian; Chalkiadaki, Maria-Anna; Mangla, Anurag, "Low-power analog/RF circuit design based on the inversion coefficient," in ESSCIRC 2015 - 41st , vol., no., pp.202-208, 14-18 Sept. 2015

Abstract: This paper discusses the concept of the inversion coefficient as an essential design parameter that spans the entire range of operating points from weak via moderate to strong inversion, including velocity saturation. Several figures-of-merit based on the inversion coefficient, especially suitable for the design of low-power analog and RF circuits, are presented. These figures-of-merit incorporate the various trade-offs encountered in analog and RF circuit design. The use of the inversion coefficient and the derived figures-of-merit for optimization and design is demonstrated through simple examples. Finally, the simplicity of the inversion coefficient based analytical models is emphasized by their favorable comparison against measurements of a commercial 40-nm bulk CMOS process as well as with simulations using the BSIM6 model.

[Purdue e-Pubs] A physics-based compact model for thermoelectric devices


A physics-based compact model for thermoelectric devices
Kyle Conrad, Purdue University; Mark S. Lundstrom, Purdue University (Advisor)

Abstract: Thermoelectric devices have a wide variety of potential applications including as coolers, temperature regulators, power generators, and energy harvesters. During the past decade or so, new thermoelectric materials have been an active area of research. As a result, several new high figure of merit (zT) materials have been identified, but practical devices using these new materials have not yet been reported. A physics-based compact model could be used to simulate a thermoelectric devices within a full system using SPICE-compatible circuit simulators. If such a model accepts measured or simulated material parameters, it would be useful in exploring the system level applications of new materials. In this thesis, the ground work for such a compact model is developed and tested. I begin with a discussion of thermoelectric transport theory within the Landauer formalism. The Landauer formalism is used as the basis of the tool LanTraP, which uses full band descriptions to calculate the distribution of modes and thermoelectric transport parameters, which can serve as the input to a compact model. Next, an equivalent circuit model is presented, explained, and tested using a simple Bi2Te 3 thermoelectric leg. The equivalent circuit is shown to perform well under a variety of DC, transient, and AC small signal operating conditions. With the equivalent circuit it is easy to determine the maximum cold side temperature drop, the maximum cold side heat absorbed, the temperature profile within the leg, the temperature response to a pulsed current, and impedance over a range of frequencies. Finally, Sentaurus®, a computer program that solves the thermoelectric transport equations numerically, is used to compare and benchmark some of the results of the equivalent circuit when considering Si as the thermoelectric material. The equivalent circuit and Sentaurus® simulations produce similar results in DC and transient cases, but in the AC small signal case the two simulations produce slight differences. The results of this work establishes a baseline compact model for thermoelectric devices whose accuracy and capabilities can be extended.

[video] How to Model a BJT Bipolar Junction Transistor

This video covers the basics of bipolar junction transistor (BJT) modeling and illustrates an easy step-by-step procedure to extract the model parameters of the popular Gummel-Poon (GP) model. While the GP model was introduced in the early 1970’s, it still enjoys a wide popularity in electronic device modeling and many modeling engineers consider it a classic and an excellent starting point for getting familiar with modeling in general.

Compact Modeling Marie Sklodowska-Curie Postdoctoral Fellowship in Spain

The European (Horizon 2020) Call for Postdoctoral Individual Marie Sklodowska-Curie Fellowships (H2020-MSCA-IF-2015) is open until September 10 2015.

I am looking for one or two candidates to work in my research group at the Universitat Rovira i Virgili (Tarragona, Spain) in the field of compact modeling of advanced semiconductor devices. Therefore, I would like to receive CVs from potential applicants. Once I have selected the candidates, we will make the application.

The candidates must have a Ph D in Electrical Engineering, Electronic Engineering, Physics, Telecommunication Engineering, or related subjects.

Candidates from all countries can apply for an Individual European Fellowship provided they have not sepent more than 12 months during the last 3 years in the country of the Host Institution (in this case, Spain)

These felowships can be for one or two years. Salaries are extremely good and the prestige of having this type of fellowship is very high. For this reason, there is a tough competition to get these fellowships.

I am looking for candidates for these Marie Curie Grants, both from Europe and outside Europe. Candidates must have a good CV (preferably with more than 4 publications as first author in international journals, in order to have chances). In order to fit the Marie Curie requirements, their age should be below 35.

If successful, the postdoctoral researchers will work on the characterization of compact modeling of any of the advanced semiconductor devices targeted by our research European projects: organic and oxide TFTs, advanced III-V HEMT and III-V MOSFETs,  SOI and Multi-Gate MOSFETs, tunnel FETs.

The specific device/s in which the postdoctoral researcher will work will depend on his/her preference and background.

Candidates must send me by e-mail (to benjamin.iniguez@gmail.com) a CV or resume by AUGUST 31 2015. Successful applicants will be informed by SEPTEMBER 2, and then we will start to make the application. The successful candidates will be informed on the steps to do.

Tarragona is a small city (110000 inhabitants) on the Mediterranean coast, about 100 Km south from Barcelona, and very well connected to Barcelona and the main Spanish cities by rail and highway. Tarragona is a very old city, very important during the Roman Empire, and with a lot of historical landmarks.

The quality of life in Tarragona is excellent. Mediterranean and mild climate the whole year. Wonderful beaches around the city (even at the city). Mountains close to the city (even the Pyrenees are not far). Besides, the city is very quiet, but with an intense nightlife.

My research group in the Department of Electronic Engineering, Universitat Rovira i Virgili (URV) is one of the strongest groups in compact modeling in Europe. We are leading one European project on compact modeling of organic and oxide TFTs (in which a total of 9 European universities and companies participate). We also participate on  other projects targeting other advanced devices.

I am looking forward to receiving excellent applications!

Best Practices for Compact Modeling in Verilog-A

Mcandrew, C.C.; Coram, G.J.; Gullapalli, K.K.; Jones, J.R.; Nagel, L.; Roy, A.S.; Roychowdhury, J.; Scholten, A.J.; Smit, G.D.J.; Wang, X.; Yoshitomi, S., "Best Practices for Compact Modeling in Verilog-A," Electron Devices Society, IEEE Journal of the , vol.PP, no.99, pp.1,1

doi: 10.1109/JEDS.2015.2455342

Abstract: Verilog-A is the de facto standard language that the semiconductor industry uses to define compact models. Unfortunately, it is easy to write models poorly in Verilog-A, and this can lead to unphysical model behavior, poor convergence, and difficulty in understanding and maintaining model codes. This paper details best practices for writing compact models in Verilog-A, to try to help raise the quality of compact modeling throughout the industry.

Analog CMOS from 5 micrometer to 5 nanometer

 Sansen, W., "1.3 Analog CMOS from 5 micrometer to 5 nanometer," ISSCC 2015 IEEE International , vol., no., pp.1,6, 22-26 Feb. 2015 doi: 10.1109/ISSCC.2015.7062848 
Abstract: In our future, as usual, analog designers will continue to expand their expertise and knowledge in response to changing needs. While devices will change their nature and operate at higher and higher frequencies, their I-V characteristics will remain similar. In the near term, increased speed of MOS circuits, will be reached by operating deeper in weak inversion. Offset and 1/f noise will continue to play a critical role. Thus, in general, it seems that analog expertise is insensitive to technology change.
