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 ...

Learn about the working principles of Phase-Locked Loops (PLL) and why they are widely used for applications where frequency tracking, resonance driving, and oscillator control are required.

Editor's Note: Although the primary target market for the 86100CU-400 application presented below is for ASIC/SoC designs, I'm assured by the folks at Agilent that this application is also applicable ...

Some brief theory and typical measurements of phase noise. How to produce the lowest phase noise at a PLL output. A standard design procedure for a typical Type 2, second-order loop. As stated in ...

Radiation-hardened phase-locked loop (PLL) circuits represent a critical advancement in safeguarding electronic systems against the deleterious effects of ionising radiation. These circuits are ...

Dual-frequency resonance tracking (DFRT) is a technique that utilizes contact mode atomic force microscopy (AFM) to measure a sample’s weak electrical or mechanical responses. Conventional resonance ...
