UJT relaxation oscillator (Sweep circuit with UJT switch)

Construction of UJT relaxation oscillator The sweep circuit can be obtained with the help of unijunction transistor (UJT). The capacitor (C) start charging through the resistor (R) till the capacitor reaches the maximum voltage level VP, when

What is an Oscillator?

The oscillator circuit is made up of two reactive elements inductor and capacitor. It is also known as tank circuit. In electronic circuit it produces a periodic, oscillating electronic signal often a sine wave or a square

V-I characteristic of tunnel diode

It immediately conducts the diode when forward biased voltage is applied. The current is increases to its peak point value (Ip). The diode currents starts decreasing till it reaches its minimum value called valley point current (Iv)
