Abstract
A conversion circuit for converting a differential signal into a single-phase signalhas a source-follower amplifierand a source-grounded amplifier. The source-follower amplifieroutputs a non-inverted signal IN of the differential signal the phase of which is not inverted. The source-grounded amplifierinverts an inverted signal INX of the differential signal and adjusts its phase to that of the non-inverted signal IN. At point A, differential signals IN, INX are added and output as a single-phase signal OUT.
