ABSTRACT:
A clock signal generation apparatus containing variable delay devices for varying the delay time of two-phase clock signals used in a load circuit that uses non-overlap clock signals; a non-overlap detector for detecting a non-overlap time in the H-level zones of the two-phase clock signals and outputting a detection signal corresponding to the non-overlap time; and a control signal generation section for generating a control signal that is used to control the variable delay devices on the basis of the detection signal from the non-overlap detector, and capable of securely generating the two-phase clock signals having an optimal non-overlap time while absorbing fluctuations due to temperature characteristics, power supply voltage characteristics and individual differences in components.
