Abstract :
This paper presents a new current copier which uses a differential-pair as its storage cell. The differential-pair storage unit (DPSU) significantly reduces clock-feedthrough errors and achieves high linearity, large dynamic range, and less cross-talk noise. The high performance DPSU can be used to designed a fully differential switched-current ADC to improve performance
