temperature stable oscillator

Posted on Oct 1, 2012

The Colpitis sinusoidal oscillator provides stable output amplitude and frequency from 0°F to +150°F. In addition, output amplitude is large and harmonic distortion is low. Oscillation is sustained by feedback from the collector tank circuit to the emitter. The oscillator's frequency is determined by: Potentiometer R3 is an output level control. Control Rl may be used to adjust base bias for maximum-amplitude output.
