RC Phase Shift Oscillator Using Transistor (BJT): Circuit & Working

In this section we would like to introduce you a transistor oscillator circuit, called as RC Phase shift Oscillator. First of all we need to know what is an oscillator. An oscillator is an electronic circuit which acts as a sine wave generator. The only requirement of an oscillator is a DC power supply source. It is widely used in frequency variable signal generators, so it is a common basic electronic circuit.

Wein Bridge Oscillator using ic 741 op amp

Wien bridge oscillator is an audio frequency sine wave oscillator of high stability and simplicity. Before that let us see what is oscillator? An oscillator is a circuit that produces periodic electric signals such as  sine wave or square wave. The application of oscillator includes sine wave generator, local oscillator for synchronous receivers etc.

RC Phase shift Oscillator using 741 op amp- Design and output waveform simulation

RC phase shift oscillator is a sinusoidal oscillator used to produce sustained well shaped sine wave oscillations. It is used for different applications such as local oscillator for synchronous receivers, musical instruments, study purposes etc. The main part of an RC phase shift oscillator is an op amp inverting amplifier with its output fed back into its input using a regenerative feedback RC filter network, hence the name RC phase shift oscillator.
