Colpitts oscillator

[′kōl‚ṗits ‚äs·ə‚lād·ər]
(electronics)
An oscillator in which a parallel-tuned tank circuit has two voltage-dividing capacitors in series, with their common connection going to the cathode in the electron-tube version and the emitter circuit in the transistor version.

A novel transformer coupled Colpitts oscillator is used to achieve lower power consumption (250uW) as well as the lower close-in phase noise performance (217 FoM) compared to conventional Pierce and Colpitts oscillators [7].
Transformer Coupled Colpitts Oscillator. Transformer coupled Colpitts oscillator is used to generate the reference clock as shown in Figure 6 [7].
Then the oscillator frequency of the Colpitts oscillator circuit will be [[omega].sub.0] + [[omega].sub.[DELTA]Z].
Figure 1 shows the schematic of a high temperature Colpitts oscillator built aroundaccording to "Wireless Telemetry Electronic Circuitry for Measuring Strain in High Temperature Environments." This is a voltage controlled oscillator, which generates the radio frequency [RE] carrier and modulates the sensor information onto the carrier for wireless transmission.
