PUT Controlled Sawtooth Wave Generator

jojo February 25, 2010 No Comments
A PUT controlled sawtooth generator circuit is shown in figure. When power is first applied, the programmable unijunction transistor (PUT) is off. The capacitor C begins to charge up and the output voltage rises. This continues until the output...

GTO Sawtooth Wave Generator

jojo September 17, 2009 No Comments
A simple sawtooth generator using a GTO and a Zener diode is shown in figure. When the supply is switched on, the GTO will turn on, resulting in the short-circuit equivalent from anode to cathode. As a consequence the...
