Design an oscillator using an op-amp with a specific feedback network. Calculate the required phase shift and gain for sustained oscillation at a frequency of 1kHz.
💡 Hint: Use known frequency response formulas to support your calculations.
Suppose a particular oscillator exhibits a phase shift of 270 degrees; what should the additional phase shift be to meet the Barkhausen Criterion?
💡 Hint: Think about integer multiples of 360 degrees.
