Oscillators

The FK0800004 is an oscillator in electronic engineering, which is used to generate an electric signal of a certain frequency. The circuit mainly consists of an operating amplifier, an integrator capacitor and a signal generator. The frequency of the electric signal generated by this circuit is controlled by an external variable resistor. The operating principle of this circuit is basically the same as that of other oscillators.

Working Principle

When an input signal is applied to the operating amplifier, its output will change reversibly with the input. The output of the operating amplifier is applied to an integrator, usually formed by an RC filter, which consists of a resistor and a capacitor. The capacitor can store the output of the operating amplifier for a certain time, while the resistor controls the energy dissipation. Thus, when the input signal changes, the output signal will have a certain delay due to the charge and discharge process of the capacitor. The output of the integrator will be a signal with a sinusoidal waveform of a certain frequency. Since the frequency of the sinusoidal waveform is affected by the time constant of the RC filter, this frequency can be controlled by adjusting the values of the resistors and the capacitors.

The sinusoidal waveform generated by the integrator is then applied to a signal generator, which is usually a transistor. The signal generator can generate rectangular or triangular waveforms. It works by changing the amplitude of the applied waveform according to a predetermined pattern. The output waveform of the signal generator will be an electric signal with a certain frequency.
