Abstract
During operation of a SAR ADC, it is possible to exceed the voltage limits of a comparator by presenting voltages at the comparator input that exceed a limited range of acceptable input voltages. The present disclosure provides a system and method such as for delivering a common mode compensation voltage such that voltages present at the comparator inputs can be within the limited range of acceptable input voltages.
