Abstract :
An 8-bit 200 MHz low-power CMOS folding and interpolating analog-to-digital converter is presented. A novel mixed-averaging distributed T/H circuit is proposed to decrease the nonlinearity error of the ADC. The DNL/INL is 0.3/0.2 LSB according to MATLAB simulation results. This ADC is implemented in 0.5 um CMOS technology and the total power dissipation is merely 96 mW at a sampling rate of 200 MHz.
