Pierce harmonic oscillator

The Pierce-gate oscillator of Figure 1 is well recognized by most designers, but few understand how to specify the crystal correctly. The crystal used in the topology of Figure 1 can be either a fundamental AT-CUT or BT-CUT. A...

This plugin utilizes a quartz oscillator featuring a crystal (X1) to produce a 32,768 Hz (32,768 = 2^15) output. This frequency is fed into a 4020 14-Stage Ripple Counter, which divides the signal by 2^14, resulting in a 2...

This design circuit is intended for sine wave oscillators, providing both sine and square wave outputs across a frequency range from below 20 Hz to above 20 KHz. The oscillation frequency can be easily adjusted by changing a single...

This is a grid dip oscillator (GDO) circuit developed by Luigi Falcone. The circuit uses seven plug-in coils that cover the frequency range of 3.0 to 30 MHz. It can be connected to a frequency meter through the coaxial...

Built around a single 8038 waveform generator IC, this circuit produces sine, square or triangle waves from 20Hz to 200kHz in four switched ranges. There are both high and low level outputs which may be adjusted with the level...

An op-amp based Colpitts oscillator in Multisim displays a "timestep too small" error when the run button is pressed. Despite extensive research and attempts to resolve the issue, the error persists. The design features a C-L-C pi circuit that...
