Capacitive three-point oscillator
The capacitive three-point oscillator is an oscillator that uses an LC circuit in the feedback loop to produce the required phase shift and can be used as
a resonant filter that only passes the required oscillation frequency.
①Colpitt oscillator. As shown in the figure (a), when an external load is connected to the output of the oscillator , connect
the load with a small resistance value through capacitor coupling, or connect the load through transformer coupling to eliminate the load.
