Signal chain basics #124: Understanding VCOs integrated on silicon

It’s becoming more common to integrate voltage-controlled oscillators (VCOs) on the same semiconductor chip as the rest of the phased locked loop (PLL). This integration introduces some differences in ...

On-chip VCOs can be digitally tuned

Synchronous systems, whether analog or digital, all use a clock reference signal, typically generated using a high-frequency phase-locked loop (PLL), where power consumption, frequency range and ...

Driving the VCO in High-Voltage, High-Frequency Phase-Locked Loops

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 ...
