Title:
ONE-SHOT CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2024/045291
Kind Code:
A1
Abstract:
Embodiments of the present disclosure provide a one-shot circuit. The one-shot circuit comprises: a main one-shot circuit and a masking time window circuit. The main one-shot circuit is configured to receive, by means of a NOR gate, an input signal of the one-shot circuit, feedback of an output signal of the one-shot circuit, and a time window signal outputted by the masking time window circuit, and then to obtain the output signal after passing through a first RC time delay circuit and a logic gate, the time window signal being a signal that resists interference of an abnormal pulse of the input signal with the output signal. The masking time window circuit is configured to receive the feedback of the output signal, and then to obtain the time window signal after passing through a second RC time delay circuit and the logic gate. The problem present in existing one-shot circuits of false triggering caused by abnormal pulses of input signals is solved.
