Colpitt’s Oscillator
An oscillator is a circuit that outputs a repetitive electronic signal i.e. a sine wave.
The Colpitts oscillator was invented by Edwin H. Colpitts
The Colpitts oscillator is known for using a capacitor voltage divider as its feedback source
Advantages include:
Frequency stability
A simple and robust design
* For oscillation to occur the Barkhausen criteria must be met.
Loop Gain
Phase Shift must equal zero
Magnitude equal to unity
Realistically the magnitude will be greater than 1
* Determine if criteria is satisfied by checking the loop gain at the frequency of oscillation
