The basic components of sine wave oscillation circuit include amplifier circuit, frequency selection network, feedback network and amplitude stabilization circuit.
1. amplifier circuit: the amplifier circuit is used to amplify the amplitude of the input signal of the circuit to meet the feedback condition.
2. Frequency-selective network: The frequency-selective network is a band-pass filter, which selects a signal with a specific frequency and transmits it to the feedback network.
3. feedback network: the feedback network feeds back the output signal to the input end of the amplifier circuit to maintain the signal oscillation.
4. amplitude stabilizing circuit: the amplitude stabilizing circuit stabilizes the output of the oscillating circuit to ensure the stable amplitude of the output signal.
these components work together to generate a stable sine wave oscillation signal. Sine wave oscillation circuit is a kind of circuit that can generate stable sine wave output signal, which usually consists of an amplifier, a feedback network and a filter. It can be used in many applications, such as clock generator, audio processing, wireless communication and so on.
