    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 voltage (which is also the PUT anode voltage) is about 0.7 V above the control input (the gate voltage). The unijunction transistor is a solid state triggering device that can be used in a variety of circuits and applications, ranging from the firing of thyristors and triacs, to the use in sawtooth generators for phase control circuits.The negative resistance characteristic of the UJT also makes it very useful as a simple relaxation oscillator.
