Solution
Barkhausen conditions for sustained oscillations
The following condition called Barkhausen conditions should be satisfied for sustained oscillations in the oscillator.
- The loop phase shift must be 0° or integral multiples of 2π.
- The loop gain must be unity. |Aβ| = 1
Here; A – Voltage gain of the amplifier,
b – feedback ratio; (fraction of the output that is fed back to the input)
