ABSTRACT:
A signal generator circuit prevents a shift of a timing at which an output signal at high voltage level changes from a timing at which an output signal at low voltage level changes, and a level shifter prevents a through current from flowing between a high voltage power supply and a ground potential. The signal generator circuit has an output adjustor circuit for outputting a first output signal and a second output signal in accordance with an input signal, and a level shifter for converting a voltage level in accordance with the input signal to generate a third output signal and a fourth output signal. In response to a rising of the input signal, the first output signal first changes, then the third and fourth output signals change, and subsequently the first output signal changes.
