10 Simple Unijunction Transistor (UJT) Circuit Diagrams Explained
In the earlier post I have explained comprehensively about how a unijunction transistor works, in this post I will elucidate a few interesting application circuits using this amazing device called UJT. The example application circuits using UJT which are explained in the article are: 1) Square Wave Pulse Generator The first design below demonstrates a […]
10 Easy Op-amp Oscillator Circuit Diagrams Explained
In an op amp oscillator circuit, an op amp is configured with a resistor-capacitor feedback loop or a inductor-capacitor feedback loop, which triggers the op amp to go into an oscillating mode, generating a switching ON/OFF pulses from its output pin. The high-gain and wide passband of operational amplifier (op amp) ICs makes it possible […]
