This simulation demonstrates a 555 timer-based oscillator circuit operating in astable mode, generating a continuous square wave output. The circuit uses two resistors (1 kΩ and 2.19 kΩ) and a 1 µF capacitor to determine the oscillation frequency. The waveforms show the capacitor charging and discharging between 1/3 Vcc and 2/3 Vcc, which controls the 555 timer’s threshold and trigger pins. The output alternates between high and low states, producing a stable waveform at about 255 Hz, as shown i

This simulation demonstrates the working of an op-amp relaxation oscillator. The op-amp is configured as a comparator with positive feedback, forming a Schmitt trigger. The resistor network sets the upper and lower threshold voltages, while the capacitor continuously charges and discharges through the feedback path. As the capacitor voltage ramps up and down, it crosses these thresholds, forcing the op-amp output to switch between positive and negative saturation levels. This produces a square w
