Abstract
A differential signal generation circuit includes: an inverter array configured to sequentially invert an input signal to generate a plurality of delayed signals; and a phase mixer configured to mix a phase of a first delayed signal and a phase of a second delayed signal among the plurality of delayed signals at a preset mixing ratio to generate a first differential signal. The first delayed signal has a first delay from the input signal and the second delayed signal has a second delay from the input signal. The differential signal generation circuit is configured to generate a third delayed signal having a third delay from the input signal corresponding to a medium of the first and second delays, and the third delayed signal is further delayed to generate a second differential signal.
