摘要:
There is provided a pulse generation circuit having a small input load and capable of self-reset. The pulse generation circuit includes: a P-MOS transistor having a drain electrode connected to a first power source line; a first N-MOS transistor having a drain electrode connected to the source electrode of the P-MOS transistor; a second N-MOS transistor having a drain electrode connected to the source electrode of the first N-MOS transistor, a gate electrode connected to the input line to which an input pulse signal is input, and a source electrode connected to the second power source line; a delay circuit having an input terminal connected to the source electrode of the P-MOS transistor and the drain electrode of the first N-MOS transistor and an output terminal connected to the gate electrode of the P-MOS transistor and the gate electrode of the first N-MOS transistor; an inverter having an input terminal connected to the source electrode of the P-MOS transistor and the drain electrode of the second N-MOS transistor and an output terminal connected to the output line for outputting a generated pulse; and a keeper for keeping the voltage level of the line connected to the input terminal of the inverter.
