FET_WIEN_BRIDGE_OSCILLATOR
Used where good amplitude stability is required for wide frequency variations. Two-stage R.C coupled doss A amplifier has positive feedback loop that causes oscillation, and negative feed.buck loop that stabilizes amplitude of oscillation. Frequency ranges are 20 to 200 cps, 200 cps to 2 kc, 2 to 20 kc, and 4 to 40 kc.-L. J. Sevin, Jr., Field-Effect Transistors, McGraw-Hill, N.Y., 1965, p 113,
