Abstract
A compensation circuit for eliminating harmonic content resulting from a phase imbalance in a differential sampling circuit. The compensation circuit includes a pair of field effect transistors operating in saturation mode, each field effect transistor coupled in parallel with the differential switch of the sampling circuit, which operates in linear mode. The saturation region transistors across the differential switch allow the harmonic content to flow through the compensation circuit instead of the sampling capacitors of the sampling circuit.
