If you want a stable oscillator, you usually think of using a crystal. The piezoelectric qualities of quartz means that it can be cut in a particular way that it will oscillate at a very precise ...

Voltage-controlled oscillator-based analog-to-digital converters (VCO-based ADCs) represent an emerging class of digitisation circuits that harness the frequency-modulating properties of VCOs to ...

A phase-locked loop (PLL) is a feedback system that combines a voltage-controlled oscillator (VCO) and a phase detector in such a way that the oscillator signal tracks an applied frequency or ...

Researchers have modeled how the combination of a virtual oscillator control mechanism and a cascaded sliding mode control can help regulate voltage and frequency in a distributed-solar microgrid.

Fairview Microwave has unveiled voltage-controlled oscillators (VCOs) that allow the frequency of the output signal to be varied by adjusting the amplitude of the input tuning voltage. Unlike ...

The classic Schmitt-trigger-based RC oscillator is "hacked" and analyzed using the simulation software QSPICE.
