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!

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.
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.
