Squarewave in pspice schematics3/31/2024 ![]() The Resistors R 1 and R 2 form a voltage divider network. Ideally without any input applied the output should be zero, it is expressed as If we force output to switch between the positive saturation voltage and the negative saturation voltage at the output of an operational amplifier we can achieve square wave as an output wave. The circuit diagram of the square wave generator using an operational amplifier is shown below Square Wave Generator Circuit using Op-Amp The capacitor and resistor are connected to the inverting terminal of the operational amplifier and the resistors R 1 and R 2 are connected to the non-inverting terminal of the operational amplifier. To design the square wave generator, we need a capacitor, resistor, operational amplifier, and power supply. ![]() The basic circuit diagram and working of the square wave generator are explained below. ![]() The square wave generator is also known as Astable Multivibrator or free-running and the frequency of the square wave generator is independent of the output voltage. This generator is used in digital signal processing and electronic applications. The square wave generator is defined as an oscillator that gives the output without any input, without any input in the sense we should give input within zero seconds that means it must be an impulse input.
