Item A DC-Coupled Neural Recording Analog Front-End with Bi-Level Bulk Modulation-Based EDO Compensation in 40nm Bulk CMOS(2025)This paper presents a compact, low-power analog front-end (AFE) for high-density micro-electrocorticography (μECoG) recordings. The AFE integrates a DC-coupled, chopper-stabilized low-noise boxcar sampler, a passive switched-capacitor low-pass filter, and a 10-bit single-slope analog-to-digital converter (ADC). The boxcar sampler minimizes noise folding, enhances anti-aliasing and reduces chopping ripple. To prevent AFE saturation, a novel electrode DC offset (EDO) compensation loop is introduced. It features an embedded digital-to-analog converter (DAC) by modulating the bulk terminals of the input transistors, and a bi-level compensation scheme, thereby eliminating the requirements for high-resolution digital low-pass filters and explicit DACs typically used in traditional DC servo loops. Simulation results in 40nm bulk CMOS show an input-referred noise of 1.69 μVrms over a 1-500 Hz bandwidth, an EDO compensation range of 110 mVpp, with a power consumption of 2.28 μW and an estimated area of 0.0028 mm2 per channelItem A Wearable Dietary Monitor using a PPG-based Chewing Sensor(2016)CSEM has developed a novel wearable dietary monitoring system using a photo-plethysmography-based chewing sensor. Non-invasive, compact, and unobtrusive, it is dedicated to monitoring eating behavior and daily activity of teenagers and young adults with the aim of providing personalized guidance to tackle the ongoing obesity epidemic or eating disorders.Item Autonomous Medical Monitoring and Diagnostics(2016)CSEM has developed a platform that evaluates how data mining and machine learning can pave the way towards autonomous medical monitoring and diagnostics. Even though the original conception was oriented towards space applications, CSEM’s autonomous diagnosis platform can play an important role in many remote locations where telecommunications systems are not reliable.Item Wound Healing Monitoring System Integrating Plastic Optical Fibre Sensors(2012)A system was developed for the remote monitoring of pH and metalloproteinase in a wound dressing composed of biosensing plastic optical fibres and a modular electronic system.
