Title:
PULSE ELIMINATION CIRCUIT, AND VOLTAGE MEASUREMENT CIRCUIT AND MEASUREMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2021/203875
Kind Code:
A1
Abstract:
Embodiments of the present application relate to the technical field of circuits, and provide a pulse elimination circuit, and a voltage measurement circuit and a measurement method. The pulse elimination circuit comprises: a clock generation circuit configured to receive a logic signal and a first input signal, and generate a clock signal according to the logic signal and the first input signal; a counter connected to the clock generation circuit, and configured to receive the clock signal and count the number of periods of the clock signal to generate a second input signal; and a signal output circuit connected to the counter, and configured to provide the first input signal to the clock generation circuit and generate, according to the second input signal, a pulse elimination signal. Thus, during voltage measurement, the circuit can eliminate false triggering caused by short pulse, thereby improving the accuracy of voltage measurement.
