[mos-ak] [OpenPDK] IHP Analog Academy

IHP Analog Academy


We, IHP Analog Academy, are excited to present this deep dive into analog, RF, and mixed-signal IC design, powered by open-source FOSS CAD/EDA tools and the IHP Open PDK.

This hands-on course is designed for engineers, researchers, and students eager to gain practical experience with the SG13G2 process at the 130nm technology node. Originally hosted on-site at IHP in Frankfurt (Oder), participants spent five intensive days exploring everything from fundamental analog simulation to advanced RF, 3D EM modeling, and mixed-signal integration. And now we're excited to release it to the open-source community!

The course covers:
- Bandgap reference design and simulation using the gm/Id methodology
- RF design of a 50 GHz Medium Power Amplifier with EM simulation
- Mixed-signal integration and verification of an 8-bit SAR ADC

Each module emphasizes a real-world design flow using tools like:
ngspice, Xyce, KLayout, OpenEMS, QUCS, and Python for data analysis.

Over time, we will expand the repository with:
- More modules
- Updated toolchain support
- Improvements to existing flows

Note: This is not an introductory IC design course. A basic understanding of electronics and microelectronics is assumed. We're proud to contribute this initiative to the community to help lower the barrier to IC design using open-source tools. We encourage contributions via GitHub Issues or Pull Requests! Your feedback and contributions, are welcome!

Inclusion of Mechanical Stress Effects in a Compact MOSFET Model

Abstract: The analog performance of integrated circuits relies on stable parameters of its transistors. Mechanical stress changes the electronic properties of silicon and, therefore, also the device parameters. For circuit design, a good model of these effects is needed for a predictable and reliable function of the circuits. This article extracts the changes of various MOSFET parameters under effect of mechanical stress. A compact description of the stress effects is derived by applying tensors of piezo coefficients. The deviations are included in the physically based compact EKV model. A comparison with measured data shows that the stress effects are modelled correctly within a 10 % error margin.

[mos-ak] [Media Note] MOS-AK INAOE Workshop, Puebla (MX)

MOS-AK INAOE Workshop on Semiconductor Technologies
Puebla (MX), May 14-16, 2025

Media Note

The MOS-AK Workshop on Semiconductor Technologies was held at the Instituto Nacional de Astrofísica, Óptica y Electrónica (INAOE) in Tonantzintla, Puebla, México, on May 14-16, 2025. This workshop was sponsored by MOS-AK, the INAOE, and IEEE through the Puebla Section and the local chapters for the Electron Devices and Instrumentation and Measurements societies. The MOS-AK event was inaugurated by Dr. Wladek Grabinski representing MOS-AK and IHP; Dr. David Sánchez, INAOE's General Director, Dr. Claudia Feregrino, Director of Research and Development for INAOE, and Dr. Roberto Murphy, the local organizer.

The objective of the workshop was to present the various open source tools for the design and simulation of integrated circuits (ICs). It consisted of in person as well as remote keynote speeches by experts in the field, and of a three-hour workshop on digital design synthesis.

The opening talk was by Dr. Wladek Grabinski (MOS-AK), covering a description of all the available FOSS CAD/EDA tools and programs for the design, simulation and fabrication of ICs using OpenPDK. This was a very enlightening run-through of the opportunities that can be exploited by all those who work in the field, at all levels. 

It was followed by a conference by Dr. Joaquín Faneca Ruedas, from the Centro Nacional de Microelectrónica (CNM) in Barcelona, Spain. He spoke about silicon nitride photonics, which is fast becoming a scalable platform for integrated optics. We then had the pleasure of listening to Dr. Medhi Saligane talk on agent AI for analog layout generation. Dr. Saligane is now with Brown University in the US. The first day was closed by a talk on memristor modeling by Dr. Arturo Sarmiento from INAOE. Memristors are fast becoming a common element in IC design, and their modeling and eventual characterization has become a very important field of endeavor in recent years.

The second day was opened by Dr. Colin Shaw from Silvaco (US) who gave a deep description of the status of the Si2 Compact Model Coalition.
The rest of the morning was dedicated to a three-hour workshop on digital circuit synthesis using open source CAD/EDA design tools.

Friday's first talk was by Dr. Harriet Parnell, a senior academic engineer at Ansys, and who gave a talk describing Ansys Lumerical FDTD tool, with a case study of a nanohole array. This was followed by a description of logic technology device innovations, given by Dr. Carlos Díaz, the Senior Director for Research and Development for Taiwan Semiconductor Manufacturing Company (TSMC). This great talk was followed by a presentation of the MOSbius project given by Dr. Peter Kinget, the Bernard J. Lechner Professor of Electrical Engineering at Columbia University. The workshop was closed by a researcher at INAOE, Dr. Reydezel Torres, who spoke of the simulation of chip-to-chip interconnects, another very important aspect of semiconductor technology.

The MOS-AK INAOE workshop was attended by 86 participants, mostly undergrad students but also by professional academicians and scientists. We can call it a success, and we hope that it has contributed to the country's much-needed progress in integrated circuit design and technology.

Speaker: Dr. Xing Zhou


Abstract: As Moore's Law is slowing down and eventually approaching an end for conventional CMOS, new platforms for producing circuit-level innovation are desired. At the same time, it is not desirable to throw away the existing Si-CMOS infrastructure to start new. This talk presents an overview of the 10-year research program, which is a "vertical" innovative platform by "inserting" III-V layers into a conventional Si-CMOS foundry process. The talk also presents a unified compact model for generic GaN/InGaAs-based HEMTs in the context of the hybrid III-V + CMOS technology developed for future heterogeneous integrated circuits. The developed model has been implemented in a hybrid III-V/CMOS foundry PDK for designing heterogeneous circuits in III-V/Si monolithically co-integrated technology.

Speaker Bio: Dr. Xing Zhou obtained his B.E. degree in electrical engineering from Tsinghua University in 1983, M.S. and Ph.D. degrees in electrical engineering from the University of Rochester in 1987 and 1990, respectively. He has been with the School of Electrical and Electronic Engineering, Nanyang Technological University (NTU), Singapore from 1992 to 2024. His past research interests include Monte Carlo simulation of photocarrier transport and ultrafast phenomena as well as mixed-mode circuit simulation and CAD tool development. His research at NTU mainly focuses on nanoscale CMOS compact model development. His research group has been developing a unified core model for nanoscale bulk, SOI, double-gate, nanowire CMOS, as well as III-V HEMTs. He has given more than 150 IEEE EDS distinguished lectures and invited talks at various universities as well as industry and research institutions. Dr. Zhou was the founding chair for the Workshop on Compact Modeling (WCM) in association with the NSTI Nanotechnology Conference (2002–2018). He was an editor for the IEEE Electron Device Letters (2007–2016), a guest Editor-in-Chief for the special issue of the IEEE Transactions on Electron Devices (Feb. 2014) on compact modeling of emerging devices, and a member of the Modeling & Simulation subcommittee for IEDM (2016, 2017). He was an Elected Member-at-Large of EDS Board of Governors (2004–2009; 2011–2016) and served as Vice-President for Regions/Chapters (2013–2015). He has been an EDS Distinguished Lecturer since 2000. He is a Life Senior Member of the IEEE and currently serves as chair for the RS/EPS/EDS Singapore Joint Chapter.
