Improve phase noise by down-converting the VCO frequency

Phase noise is a critical parameter in most phase-locked loop (PLL) synthesizer applications. In radars, for example, phase noise at low-offset frequencies translates to the ability to discern between ...

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 ...
