Question A-005-001-003

How is positive feedback coupled to the input in a Pierce oscillator?

Correct Answer

Through capacitive coupling

Explanation

The Pierce oscillator is a crystal-controlled oscillator where the crystal acts as a series resonant element between the output (e.g., collector/drain) and input (e.g., base/gate) of the active device, with capacitors to ground from input and output providing the phase shift for oscillation.
