Abstract:
An interpolating comparator bank comprising:first and second differential amplifiers, each having a differential input and a differential output, with the differential input including first and second component inputs and the differential output including first and second component outputs;a first comparator circuit having a differential input and configured to provide a comparator output indicative of a polarity of a signal received at the differential input of the first comparator circuit, with the comparator differential input including first and second component inputs;a first capacitor connected to couple the first component output of the first differential amplifier to the second component input of the first comparator circuit;a second capacitor connected to couple the second component output of the first differential amplifier to the first component input of the first comparator circuit;a third capacitor connected to couple the first component output of the second differential amplifier to the second component input of the first comparator circuit; anda fourth capacitor connected to couple the second component output of the second differential amplifier to the first component input of the first comparator circuit.
