Jitter amplifier circuit, signal generation circuit, semiconductor chip, and test apparatus

摘要

There is provided a jitter amplifier circuit for amplifying jitter included in an input signal. The jitter amplifier circuit includes a distorting circuit that receives the input signal, and distorts a waveform of the input signal so as to generate a harmonic component of the input signal, and a filter that passes, out of the distorted signal output from the distorting circuit, a harmonic component of a certain order which is determined in accordance with an amplification ratio of amplifying the jitter.
