    Figure above displays a Wien-bridge oscillator circuit configured for single-frequency audio operation. This circuit which holds two 2N4340 FETs (Q1 and Q2) is a two-stage RC-coupled amplifier with a Wien bridge (C1, C2, R1 and R2 worked against R4 and R4) attached in the feedback path from the output drain (Q2) to the input gate (Q1).

    An introduction to Audio Oscillators also known as RC Oscillators. So far, we have considered the oscillators which use L-C tuned circuit that causes a phase shift of 180° due to inductive or capacitive coupling in addition to a 180° phase shift produced by the transistor itself. The oscillators employing L-C elements, called the L-C oscillators, are very popular for …
