Peak detector is used with FET operated in voltage variable.-resistance mode. in combination with standard double-integration circuit having regenerative feedback. to give 1.46-kHz sinewave output into 500-ohm load at 10 V P-P. Will operate at power supply voltages off 8 to 18 V whhout appreciable variation in output amplitude or frequency. Output varies less than 1.5% in frequency and 6% in amplitude over temperature range of 10 to 65°c. Circuit can be modified for other frequencies.-F. Macli. FET Stabilizes Sine-Wave Oscillator.
