Square Wave Using an Operational Amplifier #electronics | Electronics Byte

SQUARE WAVE GENERATOR: It's a square wave generator using an op-amp in an astable configuration. The frequency is set by POT1 and capacitor C1, and the output toggles between 0V and 5V. An LED indicates the output, and the waveform shows a clean square wave with a near 50% duty cycle. #opamp #circuitdesign #CircuitSimulation #electronics #electronicsrd #ElectronicsEducation | Electronics Education

In this simulation the square-wave source (1 ms period, 40% duty, 10% rise/fall) makes each element respond in its characteristic way: the resistor current follows the source almost exactly (i = v/R), so you see a square-like current that is essentially in-phase with the voltage. The inductor current cannot change instantly — it smooths the waveform into ramps and rounded peaks as it stores and releases energy (voltage impulses at edges produce gradual changes in i = (1/L)∫v dt).
