Abstract :
A 10b 30MS/s pipelined ADC using fully-differential switched-RC multiplying digital-to-analog converter (MDAC) is presented. It utilizes a resistive loop to reset the feedback capacitor in the MDAC without using the floating switch. The measured differential and integral nonlinearities of the prototype IC fabricated in a 0.13mum CMOS process are less than 0.54 LSB and 1.75 LSB respectively. The prototype ADC achieves 51.6dB SNARED and 65.9dB SFDR with IV supply while consuming 17mW power.
