ABSTRACT:
A differential analog to digital converter (ADC) comprises a first resistance ladder leg including two resistances having first ends that communicate with a middle node. A second resistance ladder leg includes two resistances having first ends that communicate with a middle node. A first amplifier applies a voltage based upon a first phase of an input signal to said middle node of said first resistance ladder leg. A second amplifier applies a voltage based upon a second phase of the input signal to said middle node of said second resistance ladder leg.
