The Colpitts oscillator is a time-tested design — from 1918. [The Offset Volt] has a few videos covering the design of these circuits including an op-amp and a transistor version. You can find ...

Various oscillator circuits use different designs within the amplifier block in Figure 1. The popular common-emitter or common-source transistor stage presents two important drawbacks: First, it's an ...
