The invention discloses a novel pulse-width self-adjustable pulse modulation circuit and a working method. The circuit comprises a switch driver, a forward current regulator, a reverse current regulator, and an MOS switch tube. The switch driver is electrically connected to the forward current regulator and the reverse current regulator. The forward current regulator and the reverse current regulator are electrically connected to the MOS switch tube. The novel pulse-width self-adjustable pulse modulation circuit outputs a pulse high and low level conversion speed which is a time delay betweenoutput pulse level conversion and input pulse level conversion. Conversion from high to low and from low to high is influenced by the forward current regulator and the reverse current regulator. The pulse width adjustment of an output pulse can be realized by adjusting a current flowing through the forward current regulator and the reverse current regulator.
Description
technical field [0001] The invention relates to a design method of a pulse modulation circuit, in particular to a novel pulse modulation circuit with self-adjustable pulse width and a working method. Background technique [0002] In radar microwave products, the pulse modulation circuit is mainly used to generate a power modulation output pulse according to the external input pulse to supply power to the active devices in the product, so that the radar microwave product works in pulse mode. In practical applications, the same input pulse needs to be input to multiple microwave radar products, and the startup and shutdown times of these microwave radar products are required to be different in each pulse cycle, so as to avoid mutual interference caused by simultaneous startup . Therefore, it is required that the pulse modulation circuit can realize the delay adjustment of the output pulse of the pulse modulation circuit relative to the input pulse through its own design, and ...
