As the wide band signal application popularizing,traditional ADC based on Nyquist sampling theory is limited,which can be conquered by compressed sensing theory.This paper presents an ADC based on compressed sensing theory,and put forward a calibration method to estimate the mismatch of multipath when reconstructing the original signal from compressed sensing measurement.The whole system is implemented in UMC 180 nm fabrication.It consists multipath to measure the input signal but quantized by a single quan...
