Abstract

The application provides an ultra-narrow pulse expansion circuit, method and electronic equipment. The circuit comprises: a calibration module, configured to perform inverse transformation and delay processing on a control signal to obtain a calibration signal; an OR gate, configured to perform logical OR operation on a measured signal and the calibration signal to obtain a clock signal; and a D flip-flop, configured to output an expanded signal according to the control signal and the clock signal. The input end of the D flip-flop is connected to the control signal, and the clock end of the D flip-flop is connected to the output end of the OR gate. The first input end of the OR gate is connected to the output end of the calibration module, and the second input end is connected to the measured signal. The input end of the calibration module is connected to the control signal. By using the application, the measured signal, especially the ultra-narrow pulse with multiple uncertain numbers of ultra-narrow sub-pulses, can be expanded, and the expanded pulse can be stably sampled.
