%X A conversion-precision and sampling-rate programmable pipeline analog-to-digital converter (ADC),without adjusting the bias current of operational amplifiers,is presented in this paper.This ADC achieves a conversion-precision of 8 to 11bits and a sampling-rate from 400k to 40MSa/s.To increase the power-on speed and reduce the power consumption,a novel pre-charged switched operational amplifier is proposed.The power can be significantly reduced by adopting an improved current modulated power scaling (CMPS) t...
