Oscillator circuit

摘要

In the oscillator circuit, a series resonant circuit is connected to the input of a first and to the output of a second amplifier. Between the output of the first amplifier and the input of the second amplifier, an RC band-pass filter is connected. The input impedance of the first amplifier and the output impedance of the second amplifier are low whilst the input impedance of the second amplifier and the output impedance of the first amplifier are high.
