When the voltage at the capacitor increases slightly more than the differential voltage V1. When Vin is positive the output is also positive, at this instance, the capacitor starts to charge through resistor R2 towards positive saturation voltage until V1 = V2. Therefore, input differential voltage (Vin) = V1-V2 = V1-0 = V1 The voltage difference between non-inverting and inverting terminal is referred to as differential input voltage and is given by Vin.Īt initial state when the capacitor is fully discharged, the voltage at inverting pin will be zero, i.e. Also, let us assume voltage at non-inverting terminal be V1. Let us assume the voltage at inverting terminal be V2 that equals to the voltage across the capacitor.

Working of Square Wave Generator Using Op-Amp 741 One voltage divider is designed using two resistors & is connected to output and ground at the non-inverting pin. One capacitor is connected to the inverting terminal of an op-amp with one pin connected to ground, a resistor for charging and discharging of the capacitor is also connected to the inverting terminal to output. The circuit for square wave generator using Op-Amp is shown in the figure below. input and output, this feature saves the internal circuitry of the IC from damage by overload. Moreover, the IC is also overload protected from both sides i.e. Its feature like high gain, low current consumption, and wide supply voltage makes it ideal to use in battery-operated circuits.
