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.

Emitter followers are well known for being prone to oscillation if they're feeding a capacitive load. The trait is shared however, with source followers, cathode followers ( Remember vacuum tubes?? ) ...

This is a common emitter Colpitts oscillator. R1 and R2 form a voltage divider to provide base bias. the emitter resistor R3 also provides some bias. R4 is the collector resisotr across which the any ...

In this walkthrough she demonstrates simulating a Colpitts oscillator using NI Multisim 14.3 – a deceptively simple analog circuit known for generating stable sine waves.

This paper presents the development of a low-power Colpitts oscillator for use in stand-alone sensors measuring mechanical quantities, such as force. The Colpitts oscillator, known for its ease of ...

The Colpitts oscillator output is level-shifted using R4 and R5 to a zero of about 1.2 V, which is the microprocessor's analog comparator reference voltage.

2. Colpitts Oscillator Circuit: This includes inductors, capacitors, and a transistor to create the oscillating signal. 3. Speaker: To output the audible tone when metal is detected. 4.

The phase-noise equation provides the design guideline to optimize the phase noise of the proposed Colpitts oscillator, of which the property is proven with simulation and measurement results. The ...
