ABSTRACT:
A pulse generation circuit for outputting a pulse with a predetermined waveform to an output terminal in response to a start signal includes a circuit adapted to generate a plurality of signals {Di|i denotes an integer in a predetermined range}, which has predetermined amounts of time differences from the start signal, based on the start signal, a plurality of power supplies {Ej|j denotes an integer} adopted to supply electric energy of a predetermined electric quantity, and a switching circuit adapted to sequentially switch the power supplies {Ej} in a predetermined order in accordance with logical function values of at least a part of the signals {Di} to connect the power supplies {Ej} to the output terminal.
