Question

A phase shift oscillator requires minimum gain of

• A. \(1 \)
• B. \(10 \)
• C. \(29 \)
• D. \(100 \)

Hint:

For a standard 3-stage RC Phase Shift Oscillator: - Minimum Gain required: \( A \ge 29 \) - Frequency of oscillation: \( f_0 = \frac{1}{2\pi RC\sqrt{6}} \) Always remember that if the RC network uses a different arrangement (e.g., buffered stages or FET variations), this minimum gain requirement changes, but for a standard unbuffered RC ladder network, it is always 29.

Answer 1

The Correct Option is C
