Oscillator CircuitsQ1) List the general requirements for oscillation?Ans i. For any feedback circuit the transfer function is Vout/Vin =A/1+AFor oscillations, system should be unstable so, A= -1 (Barkhausen Criterion)ii. All the oscillator circuits are composed of TLV247X OP-AMP, 5% resistors and 20% capacitors.Q2) How does an RC combination affect the phase plot of an oscillator?Ans The phase shift determines the oscillating frequency and the oscillator oscillates only on that frequency w
