Abstract:
A pulse signal generator comprising:a series connection of a pull-up transistor and a pull-down transistor between a high voltage line and a low voltage line; anda logic circuit having a first input terminal for receiving a clock signal utilizing plural clock cycles as a cycle unit and having a latch circuit for receiving said clock signal and an action commence signal and outputting a latch circuit output signal, said logic circuit having first and second output terminals connected to gates of said pull-up and pull-down transistors for outputting first and second output logic signals from said first and second output terminals and inputting said first and second output logic signals into said gates of said pull-up and pull-down transistors respectively,wherein said logic circuit controls ON-OFF operations of said pull-up and pull-down transistors independently, so that said pulse generator generates a start edge of a pulse signal in synchronizing with any one of a rising edge and a falling edge of a first cycle of said clock signal, and then said pulse generator generates an end edge of said pulse signal in synchronizing with any one of a rising edge and a falling edge of a later cycle than said first cycle.
