ABSTRACT:
A semiconductor integrated circuit has a voltage generator, a delay gate array, and a current controller. The voltage generator generates an output voltage in response to voltage control signals. The delay gate array has cascaded delay gates for producing a delay. The current controller controls a current flowing to the delay gate array in response to the output voltage of the voltage generator. Consequently, the voltage control signals control the delay produced by the delay gate array. This circuit is capable of precisely controlling the delay with a small number of elements and a small circuit scale.
