In this video, we will discuss the phase-shift oscillator circuit. This oscillator is composed of a gain stage (inverting amplifier) and a feedback network (third-order cascaded RC circuit). The circuit includes one op-amp, four resistors, and three capacitors. • We will begin with explaining the oscillation principle and the requirements for oscillation using the Barkhausen criterion. We will determine the expression of the oscillation frequency and the required gain for the gain stage of the circuit. We will use the node voltage method, the ideal op-amp characteristics, and the oscillation criterion to calculate the required component values. We will workout the calculations step by step and verify our calculations in TINA-TI Spice simulations. • 🎯 Outline: • ⏩00:00:00 Introduction • ⏩00:00:25 Oscillation Principles • ⏩00:04:17 Oscillation Condition • ⏩00:05:39 Barkhausen Criterion • ⏩00:09:04 Derivation Oscillation Frequency Formula and Required Gain • ⏩00:26:28 Design Example - Calculations • ⏩00:28:49 Design Example - Simulation Results in TINA-TI Spice • 👉 More Oscillators: • Oscillators • 👉 More Operational Amplifier Circuits: • Operational Amplifier Circuits • 👉 More Analog Electronics: • Analog Electronics • ⭐ If you have questions or comments, please let me know.
