High-Voltage-Enabled Analog/RF Circuit Techniques for Nanoscale CMOS
Pui-In (Elvis) Mak,
University of Macao – Macao, China –
Technology downscaling has led to a continuous reduction of supply voltage (VDD) to maintain device reliability. High-voltage-(HV)-enabled analog/RF circuits have emerged as a feasible alternative to cope with the nanometer technologies at low cost. An elevated VDD directly open up much flexibility in defining circuit topologies while preserving sufficient voltage headroom for signal swing. Evidently, design-for-reliability is essential to avoid overstress on each device.
This lecture starts by introducing the concept of HV-enabled analog/RF circuits. State-of-the-art works are discussed to justify their advantageous features over wide range of aspects. Our recently proposed 2xVDD RF techniques for enhancing circuit performances without leveraging reliability are then presented. A HV-enabled mobile-TV tuner RF front-end is fabricated in 90-nm CMOS 1 as a proof-of-concept prototype. It include a cascode-cascade inverter-based low-noise amplifier, a linearized programmable C-2C attenuator with a reliable overdrive control, a gain roll-off compensation path and dual cascode I/Q mixer drivers. Stress-conscious circuit topologies and gate-drain-source engineering techniques enable reliable 2-V operation with standard 1-V thin-oxide transistors.

Workshop “Metabolism and mathematical models: Two for a tango” – 2nd Edition
Title: Workshop Metabolism and mathematical models: Two for a tango – 2nd Edition
Dates: October 25-26, 2022
Location: This workshop will be held in a virtual way
The topic of this workshop is metabolism in general, with a special focus, although not exclusive, on parasitology. Besides an exploration of the biological, biochemical and biomedical aspects, the workshop will also aim at presenting some of the mathematical modelling, algorithmic theory and software development that have become crucial to explore such aspects.
This workshop is being organised in the context of two projects, both with the Inria European Team Erable. One of the projects involves a partnership with the University of São Paulo (USP), in São Paulo, Brazil, more specifically the Institute of Mathematics and Statistics (IME) and the Institute of Biomedical Sciences – Inria Associated Team Capoeira – and the other involves the Inesc-ID/IST in Portugal, ETH in Zürich and EMBL in Heidelberg – H2020 Twinning Project Olissipo.
The workshop is open to all members of these two projects but also, importantly, to the community in general.
