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 ...

Having already examined the Colpitts oscillator, we now look at its first cousin, the Clapp oscillator. Please consider the following illustration in Figure 1. There is an R-L-C network of passive ...

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 ...

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 split capacitor (as opposed to a tapped inductor).

As shown in the figure, the circuit is essentially an overtone Colpitts oscillator. Assuming transistors Q1 and Q2 are a matched pair, the current through Q2 is nearly identical to that of Q1 ...
