555 ic linear ramp sawtooth

Posted on Feb 5, 2014

The Vc1 increases linearly when the pull-up resistor RA in the mono stable circuit is replaced with constant current source, generating a linear ramp. This is the figure that shown the linear ramp generating circuit and the generated linear ramp waveforms illustration; The current flowing through capacitor C1 becomes a constant current generated b
