555 Square Wave And Sawtooth Wave Generator Circuit
As shown, 555 and R2, C1, VT1 etc. make up a monostable trigger circuit, the difference from the general trigger is thatVT1,R1,R2,R3 make up a constant current source, to charge to C1 with constant current, whichmakes C1's charging voltage linearity good and has precise delay. The delay time td≈1.1R2C1. It is required the trigger pulse cycle time T>td. The output wave is shown as picture below. (a) is circuit. (b) is wave.
