This is a simulation of RC Phase-Shift Oscillator. It generates a stable sine wave using three RC stages that provide a total phase shift of 180°, combined with an inverting amplifier for the remaining 180°. The circuit shown oscillates at approximately 50 Hz, with an output amplitude around ±6 V. It's commonly used in low-frequency sine wave generation applications #ElectronicsEducation #electronicsrd #oscillator | Electronics Education

This simulation shows a Ring Oscillator, a fundamental type of oscillator built using an odd number of inverting stages, here implemented with MOSFET inverters. Each inverter introduces a phase shift of 180°, and with three stages, the total phase shift becomes 540°, effectively 180° for sustained oscillation as per the Barkhausen criterion. The capacitors at each node determine the delay, which controls the oscillation frequency. The waveforms above display three out-of-phase outputs (blue, gre
