A low-distortion oscillator is necessary for testing today'sADCs (analog-to-digital converters) that have resolution higher than 20 ...

The oscillator uses an inverted Wien-bridge topology with amplitude stabilization through an LED-driven CdS (cadmium-sulfide) photocell isolator. Using SPICE simulations before building the circuit, ...

To test the oscillator circuit, I formed a loop at the oscillator’s output that matched the loop at the end of the Lecher line. Part of that loop is a 6.8 Kohm resistor, there so that the ...

Like many people who repair stuff, [Learn Electronics Repair] has an oscilloscope. But after using it to test a motherboard crystal oscillator, he started thinking about how people who don’t … ...

Tradeoffs: MEMS vs. Crystal Oscillators Figures 1a and 1b show block diagrams of a MEMS oscillator and a crystal oscillator circuit. The MEMS oscillator is more complicated.

Designed to control the frequency of crystal oscillator circuits, the 3022 series of high-ratio, hyperabrupt varactor tuning diodes is designed to deliver a dc bias control voltage from -0.3V to ...
