Pulse-Width-Modulating Biosignal ADC for Rapid ASIC Design and IP Core Reuse

摘要

This paper presents an integrated analog-to-digital converter (ADC) based on pulse-width modulation (PWM) employing a clocked comparator. The converter parameter resolution, sample rate, input range, and supply voltage are adjustable and make the design useful for implantable or wearable multiple biopotential recording (ExG).
