Corentin to present at ISSCC 2021

Come check out our ISSCC paper, #28.4 titled “A 400mVpp 92.3dB-SNDR 1kHz-BW 2nd-Order VCO-Based ExG-to-Digital Front-End Using a Multiphase Gated-Inverted Ring-Oscillator Quantizer.” Corentin will describe a second-order VCO-only delta-sigma ADC with a wide dynamic range (>90dB) and a high input impedance (>50MΩ) enabling the direct digitization of ExG signals even in the presence of large motion artifacts while consuming less than 6μW. Great work from Corentin Pochet, Jiannan(Jason) Huang, and Patrick Mercier!

Somok to present at ISSCC 2021

Come check out our ISSCC paper, #10.2 titled “A 139μW 104.8dB-DR 24kHz-BW CTΔΣM with Chopped AC-Coupled OTA-Stacking and FIR DACs”. Somok will present our work on “OTA-Stacking” to improve the noise efficiency of circuits. Having already shown the benefit of this technique in an ultra-low power ECG amplifier, we demonstrate how this can be used in an analog-to-digital converter (ADC) with state-of-the-art performance. Congrats, Somok Mondal and Omid Ghadami! Also, a post on the JSOE blog here.

Ultra-Low Power, PVT-robust Transmitter Published

Somok’s paper titled “A 67-μW Ultra-Low Power PVT-Robust MedRadio Transmitter” was presented last week at a (virtual) RFIC symposium. Check out his paper, slides, and recorded talk. Impressively, this work achieves the best energy-efficiency (67 pJ/bit) and lowest power among sub-1mW transmitters!

Congratulations, Dr. Zhou!

Congratulations, Dr. Zhou! Xiahan successfully defended his thesis on Magnetoresistive Biosensors. Check out some of his work here, here, and here. It was our group’s first “virtual” Zoom defense. Xiahan will start at Qualcomm soon.

Congratulations, Matthew!

Congratulations, Matthew for winning the ECE undergraduate research award! Matthew is an amazingly hard worker and has been very productive in his time working with the BioEE group. We will miss him! Matthew will join the CMU Ph.D. program in the fall.

Congratulations, Dr. Mondal!

Somok successfully defended his thesis titled, “Power-Efficiency Enhancement Techniques for Precision Sensing Circuits and Short-range Transmitters.” We celebrated his achievements with a “chip cake!” (If you are unfamiliar with this tradition, check out this video.) Also, check out some of Somok’s chips here.
