Abstract :
Presented here is a 10 bit SAR ADC working over a wide supply range of 5.5 V to 2.5 V. The circuit is built in a CMOS process with Metal-Poly capacitors. Issues related to low voltage sampling circuitry design and low voltage high speed comparator design are discussed. Silicon evaluation results are presented
