Common RC sine wave oscillator circuit is RC series-parallel sine wave oscillator circuit. It is also called Wien bridge sine wave oscillator circuit. Series-parallel network here is regarded as an option for frequency and feedback network. The circuit is just shown in Figure (1): Its starting condition is and its oscillation frequency is .It is mainly used for low-frequency oscillations. To generate a higher frequency sinusoidal signal, the LC sine wave oscillator circuit is generally adopted. Its oscillation frequency is . Quartz oscillator is characterized by its particularly stable oscillation frequency, so it is commonly used in occasions with highly stable oscillation frequency.
