Abstract
A differential flash ADC includes an input follower differential input stage for receiving a differential input signal. The outputs of the differential input stage are coupled to legs of a differential resistive ladder having nodes cross-coupled to the inputs of a comparator array. Each leg of the differential resistor ladder is terminated by a current source.
