Abstract
A signal conversion circuit for converting an inputted differential signal into a single-ended signal comprises a differential amplifier circuit for amplifying the differential signal, and generating a first non-inverted signal and a first inverted signal being inverted the first non-inverted signal, a first inverter for generating a second non-inverted signal being inverted the first inverted signal and an interpolation unit for interpolating a phase difference between the first non-inverted signal and the second non-inverted signal.
