Low noise front-end and ADC for real-time ECG System in CMOS process

"This paper presents the design and experimental results of a digital acquisition system based on a chopper-stabilized Instrumentation Amplifier with Common-Mode feedback for CMRR enhancement. Chopping techniques are used to remove both offset and flicker noise, detrimental effects characteris...
