Pulse Generator Circuit of CA3130

Published:2011/7/7 14:27:00 Author:Michel | Keyword: Pulse Generator, Circuit | From:SeekIC

This picture is pulse generator circuit composed of CA3130 etc.This circuit uses VD1 and VD2 diode (2 SK30)with high reverse resistance,which makes the charging and discharging time constant adjusted independently.R1, R2, R3 and A1 constitute comparator and S1 connects different capacity capacitors to obtain different period pulse signal. The high and low PWL timeof output waveformcan be set independently and high PWL time is determined by resistance value setting and low PWL time is decided by RP2 resistance value setting.According to the circuit components parameters, and the output pulse cycle is 4 u 5 ~ 1 S.
