Abstract

This research report describes a method for designing a Colpitts oscillator using S-parameters. The oscillator components are grouped into three functional blocks: 1) an unstable active network (which includes the transistor, feedback capacitor, and input resistor); 2) an output matching network (which includes the inductor, tuning capacitor, and load); and, 3) an input matching network (which consists of the remaining tank capacitor). This configuration not only satisfies the standard Colpitts oscillator topology, but allows the use of three simple criteria (based on the network S-parameters) to predict oscillation. A computer program was developed to calculate specific tank component values based on these criteria. An example oscillator (at 100 MHz) was built to verify the procedure.
