A Colpitts oscillator is the electrical dual of a Hartley oscillator. The Hartley oscillator is an LC electronic oscillator that derives its feedback from a tapped coil in parallel with a capacitor. http://en.wikipedia.org/wiki/Colpitts_oscillator http://en.wikipedia.org/wiki/Hartley_oscillator ~MECHASUN~ A Colpitts oscillator is the electrical dual of a Hartley oscillator.

whatever works at the desired operating frequency

An oscillator has a tuned circuit (inductance+capacitance) to determine the frequency. When the inductor is tapped to give the required phase-shift for oscillation it is a Hartley oscillator. When the capacitance is tapped it is a Colpitts.

advantages over what? Colpitts? Mostly the fact that it does not require a choke. A Hartley is more harmonic-rich than a Colpitts, so the main reason it is used lies in its (relative) ease of construction.

for radio frequnency ... and audio frequency. I have a Colpitts oscillator on a small piece of Veroboard 3/4"x 1/2"mounted on the terminals of a standard telephone earpiece. It uses the earpiece itslef as the inductor. The nominal impedance of the earpiece is about 300 ohms. With capacitors of 1μF and 0.47μF it oscillates at about 2kHz.

A. Russell Colpitts was born in 1906.
