We’ve read a lot about oscillators, but crystal oscillators seem to be a bit of a mystery. Hobby-level books tend to say, build a circuit like this and then mess with it until it oscillates.

A crystal is also more stable than typical ... The post looks at a Colpitts oscillator. You can usually tell a Colpitts oscillator by remembering it starts with C and the feedback loop has a ...

The two persons above are the geniuses who gave us two classic oscillator circuits as shown in Figure 1. Figure 1 The two classic oscillators circuits: Colpitts (left) and Clapp (right). However, a ...

Colpitts oscillator, Wien bridge oscillator, phase-shift oscillator and crystal oscillator, and the switching oscillators, popularly known as multivibrators. Concept of Feedback Incorporating feedback ...

Notice the configuration is the familiar common-emitter Pierce oscillator. In Figure 2-4D the circuit is again redrawn, this time with the base selected as ground reference. The result is the familiar ...
