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. We may also share this information with third parties for this purpose.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.

An example LTspice simulation is also provided below for your reference. More information on the pulse, sine, exponential, single frequency FM and an arbitrary piece-wise linear functions is available in the LTspice help file (F1). PWL TIME_SCALE_FACTOR=0.5 VALUE_SCALE_FACTOR=2 (0 0. A trigger expression that turns the source on as long as the expression is true.Here are some highlights of the undocumented features for the PWL fuction: To explore these features you will need to directly edit by right-clicking on the source symbol's text in the schematic editor rather than using the source component editor. These two examples use an undocumented repeat feature of PWL function. Triangular & Sawtooth Waveform Generated from Piece-Wise Linear Fuction
Waveforms for these two fuctions are show on the top of the page.
The PULSE function can be further modify to best match your simulation needs. Likewise, to create a sawtooth fuction you cab set the rise time equal to the period and the fall time to zero. For the triangular waveform you can set the rise and fall time equal to 1/2 of your desired period in your pulse function. PULSE(Voff Von Tdelay Trise Tfall Ton Tperiod Ncycles)Ī simple approach to creating a triangular and sawtooth waveform is using the PULSE fuction using the source component editor shown above. You can omit Ncycles if you need a free-running square waveform. PULSE fuction is often used in transient circuit simulation where we want the source to behave like a square wave.
