Experiment No. 8 PHASE SHIFT OSCILLATOR USING OPAMP …

Electronic Circuits Lab, Department of Electrical Engineering, College of Engineering Trivandrum 1 Experiment No. 8 PHASE SHIFT OSCILLATOR USING OPAMP AIM To design an RC PHASE SHIFT OSCILLATOR USING op-amp for a given frequency of 1kHz. THEORY An OSCILLATOR is a circuit that produces a periodic waveform on its output with only the dc supply voltage as a required input. A repetitive input signal is not required but is sometimes used to synchronize oscillations. The output voltage can be either sinusoidal or non-sinusoidal, depending on the type of OSCILLATOR . Two major classifications for oscillators are feedback OSCILLATOR and relaxation oscillators . Conditions for oscillation 1. The PHASE SHIFT around the feedback loop must be effectively zero degrees. 2. The voltage gain, ACL around the feedback loop (loop gain) must equal to (or greater than) one. The voltage gain around the closed feedback loop, ACL, is the product of the amplifier gain, Av, and the attenuation, B of the feedback circuit.

RC phase-shift oscillator is a linear electronic oscillator circuit that produces a sine wave output. It consists of an inverting amplifier element such as a transistor or op-amp with its output fed back to its input through a phase-shift network consisting of …

In Figure 7, the transistor has a positive power supply with ground on the emitter. If the input is also positive, the transistor will conduct. Figure 7 NPN Transistor-Conducting If the input goes negative, as in Figure 8, the conduction of the device stops because the input, or in this case the base junction, controls the transistor condition.
