Abstract

The invention discloses a discontinuous wave pulse signal generation method. The discontinuous wave pulse signal generation method is realized based on a pulse wave generation circuit; after being converted through a DA digital-to-analog circuit, an input signal forms an analog signal; after being filtered through a filter circuit composed of R0 and C3, the analog signal is amplified through an operational amplifier, so that an amplified signal is formed; a constant-flow source is output through a PMOS transistor, and input into an output transformer T1; simultaneously, a clock lead 1 and a clock lead 2 are connected through an external single-chip microcomputer; the output sequence of the output transformer T1 is adjusted and controlled; and thus, a high-precision and high-stability discontinuous wave pulse signal is obtained.

Description

technical field [0001] The invention relates to the field of electricity, in particular to a method for generating a discontinuous wave pulse signal. Background technique [0002] For the traditional pulse wave generating circuit, due to the low precision of the DA output used in the system, the accuracy of the entire pulse generating circuit is low, and the Ic current of the triode is sensitive to temperature and other shortcomings. The precision of the pulse generator DA has a great influence on the precision of the whole product. The present invention, aiming at the above-mentioned shortcomings, has invented a new type of pulse wave generating circuit, which adopts high-precision DA and adds a MOS tube circuit. The circuit is simple, high in reliability, and The temperature stability is high, the current loss is small, and the circuit can withstand a wider input voltage range. Improving the DA accuracy makes the circuit output current step finer and the output current mo...
