Abstract
An analog-to-digital converter circuit is described. The analog-to-digital converter circuit comprises an amplifier circuit configured to receive a differential analog input signal at a first amplifier input associated with a first amplifier current path and a second amplifier input associated with a second amplifier current path, and to generate an amplified differential analog input signal at a first amplifier output associated with the first amplifier current path and a second amplifier output associated with the second amplifier current path; a first capacitor coupled between the first amplifier input and the second amplifier output; a second capacitor coupled between the second amplifier input and the first amplifier output; and a latch circuit having a first latch input coupled to the first amplifier output and a second latch input coupled to the second amplifier output, wherein the latch circuit is configured to generate a differential digital output signal, based upon the amplified differential analog input signal, at a first latch output and a second latch output.
