A recent post presented the Colpitt’s oscillator starting point with a schematic and simulation results. In addition, it also provided a link to the recent book by Ain Rehman on this oscillator available from Amazon that contains design information and an exhaustive list of references for further study for interested readers. This post suggests downloading the Colpitt’s oscillator frequency calculator from the SPG website. It provides a good starting point and sanity check on the design of a Colpitt’s oscillator for the user. Please visit the SPG website and look under the ” Complementary” menu item.

This post describes a wideband amplifier designed in bipolar, CMOS, BiCMOS orSiGe technology. The circuit architecture is fairly simple to understand.
