Colpitts Oscillator Schematic. Supply current at 9v is around 20ma. Xc1 xc2 xl the same as for the hartley oscillator circuit.
Colpitts oscillator oscillator is an amplifier with the positive feedback and it converts dc input signal into ac output waveform with certain variable frequency drive and certain shape of output waveform like sine wave or square wave etc by using the positive feedback instead of input signal. It is another type of sinusoidal lc oscillator and is basically a harmonic oscillator which has a lot of applications. Xc1 xc2 xl the same as for the hartley oscillator circuit.

Figure 1 schematic of a collpitts oscillator perhaps the simplest colpitts oscillator to construct and get running is the series tuned version more often referred to as the clapp oscillator. Because there is no load on the inductor a high q circuit results with a high l c ratio and of course much less circulating current. The colpitts oscillator uses a capacitive voltage divider network as its feedback source.
