Working Principle:

The SIT8208AC-G3-33S-28.636300X Oscillator works on the principle of negative resistance in an amplifier. The circuit is designed to produce an amplified sinusoidal wave that is uniform in amplitude and frequency.

The negative resistance in the oscillator produces a negative gain when the frequency of the sinusoidal wave is below the resonance frequency. The negative gain causes the oscillator to become insensitive to amplitude changes, providing an accurate and consistent sine wave output.

Above the resonance frequency, the negative resistance produces a positive gain. This positive gain serves to increase the oscillator circuit’s sensitivity to changes in amplitude. In this way, the output of the oscillator is continuously adjusted by the negative gain and positive gain of the amplifier, maintaining a precisely defined sine wave signal.
