ABSTRACT:
A short pulse rejection circuit is disclosed. The circuit comprises a signal transition detecting circuit, a control signal generating circuit, a capacitor resetting and charging circuit, and a charge pulse detecting circuit. The signal transition detecting circuit is to output detecting pulses in response to any input pulse. The control signal generating circuit generates two control signals for capacitor charging and discharging in response to the detecting pulses. The capacitor resetting and charging circuit generates discharging and charging signals in response to two control signals. The charge pulse detecting circuit generates output enable pulse and outputting a short pulse rejected pulses in response to the charging signals and original input pulse.
