How would you explain phase shift oscilater?
A phase-shift oscillator is a linear electronic oscillator circuit that produces a sine wave output.
Why is the R-C oscillator also called a phase shift oscillator?
The R-C oscillator is also called a phase shift oscillator because the R-C filter creates a phase shift from input to output. The feedback portion of the oscillator (an amplifier) then serves to pump energy back into the filter.
What are disadvantage of lc oscillator over the RC oscillator?
DISADVANTAGES OF RC PHASE SHIFT OSCILLATOR.1. The output is small due to smaller feedback. 2. It is difficult for the Circuit to start oscillations.3. The Frequency stability is not so Good.4. It requires high Vcc. For large feedback.
How to design a phase shifter circuit using operational amplifier to have a desired phase shift?
There are many phase shift oscillator circuits on the internet. Google search, `phase+shift+oscillator+schematics` and `phase+shift+oscillator+diagrams`. Generally, if you want to change the phase shift characteristics, you'll need to substitute some fixed resistors with variable resistors and depending where they're placed, you can either change the operating frequency or the waveform characteristics.
How operational amplifier works as an oscillator?
A: Very easy to do just provide a positive feedback and/or a phase shift it will oscillate
What is the difference between wien-bridge oscillator and phase-shift oscillator?
Rc phase shift uses negative feedback.. Weinbridge uses both +ve and -ve feedback

Viva questions for RC phase shift oscillator?
A phase-shift oscillator is a simple electronic oscillator circuit. It consists of an inverting amplifier element such as a transistor or op amp, with its output fed back into its input through an filterconsisting of a network of resistors and capacitors. The feddback network 'shifts' the phase of the amplifier output by 180 degrees at the oscillation frequency, to give positive feedback.[1] Phase shift oscillators are mostly used at lower frequencies, often in the audio frequency range as audio oscillators.
