Colpitts Oscillator Circuit. Colpitts oscillator theory it consists of a tank circuit which is an lc resonance sub circuit made of two series capacitors connected in parallel to an inductor and frequency of oscillations can be determined by using the values of these capacitors and inductor of the tank circuit. The frequency of oscillations can be obtained by taking the values of the capacitors and inductors into consideration.
Colpitts oscillator works with a combination of inductors and capacitors by forming an lc filter. The frequency of oscillations can be obtained by taking the values of the capacitors and inductors into consideration. Colpitts oscillator was invented by american scientist edwin colpitts in 1918.
A colpitts oscillator looks just like the hartley oscillator but the inductors and capacitors are replaced with each other in the tank circuit.
The colpitts oscillator design uses two centre tapped capacitors in series with a parallel inductor to form its resonance tank circuit producing sinusoidal oscillations in many ways the colpitts oscillator is the exact opposite of the hartley oscillator we looked at in the previous tutorial. The colpitts circuit like other lc oscillators consists of a gain device such as a bipolar junction transistor field effect transistor operational amplifier or vacuum tube with its output connected to its input in a feedback loop containing a parallel lc circuit tuned circuit which functions as a bandpass filter to set the frequency of oscillation.
