摘要
The design and implementation of a chopper-stabilized switched-capacitor front-end for peripheral nervous system (PNS) recording are presented. Using a closed-loop windowed integration sampling (CLWIS) technique, the input signal is sampled directly and amplified with neglectable noise aliasing and high accuracy and linearity. By aligning the chopping and integration sampling frequencies, the chop...
