FEEDBACK_OSCILLATOR

C1 provides positive feedback between amplifier V2 and cathode follower V1, causing oscillation at frequency and amplitude at which loop gain is unity. Twin-T network in negative feed-back loop maintains pure sine wave, free of harmonics. Variable-gain negative-feedback amplifier V3-V4 stabilizes frequency and amplitude at prescribed values.-Oscillator Patent is Granted, Electronics, 31;37, p 108.
