The most stable sinewave oscillator with most simple circuit is

For sustaining oscillations in an oscillator

If Barkhausen criterion is not fulfilled by an oscillator circuit, it will

Frequency stability in an oscillator can be achieved by

Gain stability in an oscillator is usually achieved by

The fundamental requirement for oscillations in an amplifier is

Which of the undergiven oscillator has best frequency stability?

An oscillator that consists of two interdependent circuits such that output of each controls the input of the other is called a ? oscillator. in cascading, each stage's Vc gets larger which leads to ct.,-off after a few stages when Vc becomes equal to Vcc they provide low amplification per stage

The Wien-bridge oscillator is
