For input signals with high noise, a two-transistor cascoded SO is preferable. The output buffer, Q2 , provides protection between the oscillator and the output world. However, if you want to simplify ...

This FM oscillator can be used for wireless audio, microphone and part-15 applications where stable frequency modulated oscillators is needed. Lt can be varied to cover 75 to 150 MHz, as needed. FM ...

Oscillator sweeps from 20kHz to 20Hz controlled by sponge capacitor. Sponge material shows an extremely large dielectric constant (>1k), enabling a wide range variable capacitor when clamped ...

For [Grug Huler], this was one of those “just for funsies” projects stemming from a data sheet example circuit showing a bulb-stabilized LM386 audio oscillator.

The GPS receiver PPS signal is buffered by U2B to provide LED output, U2C to provide buffer drive for an external circuit, and the missing pulse detector built around U1. This will generate a low ...

Offering broader coverage than other oscillator design books on the market, this comprehensive resource considers the complete frequency range, from low-frequency audio oscillators to more complex ...
