Abstract
A semiconductor integrated circuit capable of reducing the influence of the difference in ambient temperature etc. and realizing a stable phase adjustment circuit has been disclosed. The semiconductor integrated circuit comprises a delay time adjustment circuit for delaying the rising edge or the falling edge of an input signal and changing the amount of delay, a comparison circuit for comparing an output signal from the delay time adjustment circuit with a predetermined voltage, a high-level shift circuit for shifting an output signal from the comparison circuit into a signal on the basis of an output reference voltage, and an output amplifier circuit for amplifying an output signal from the high-level shift circuit and outputting a signal for driving the semiconductor device, wherein the delay time adjustment circuit, the comparison circuit, the high-level shift circuit, and the output amplifier circuit are formed on a single chip.
