In this chapter we describe an important electronic circuit, the phase-locked loop (PLL). We first investigate the circuit’s dynamics without and with random perturbations, but in the absence of external forcing. Then we analyze the response of the circuit to noisy external signals, and we describe a method for extracting signals from the result.

A phase-locked loop (PLL) is an electronic system which synchronizes an internal oscillator, in frequency and phase, with an external signal. As brought out below, the PLL is extremely useful for signal processing and signal synthesis [41]. PLLs have been used extensively in the electronic tuning of radios and in the signal processing within TVs. Today,

Proceedings of the IEEE, 1975
A phase locked loop, (PLL), is basically a closed loop feedback system, the action of which is to lock or synchronise the frequency of a controlled oscillator to that of an incoming signal. Phase lock principles are by no means new, synchronous reception of radio signals using PLL techniques was described as early as 1932.

Arguably the most important circuit in modern electronics is a PLL. A PLL is embedded into virtually every piece of modern electronic equipment: computers, wireless communication systems, and test equipment, to name a few. What is more, each of the subsystem blocks inside these systems may contain their own PLL sub-circuit manufactured in an IC ...

Review of Scientific Instruments, 2001
In this article, a phase-locked loop (PLL) is introduced. The proposed PLL, denoted by NPLL, is similar to the standard PLL except that it incorporates a nonlinear element and a low pass filter in its loop. The NPLL outperforms the standard PLL: (i) it has a large acquisition range, i.e., it can achieve locking in situations where the standard PLL ...

A low-noise and fast-locking phase-locked loop
Proceedings of the 2003 American Control Conference, 2003., 2002In this article, a phase-locked loop (PLL) is introduced. The proposed PLL, denoted by NPLL, is similar to the standard PLL except that it incorporates a nonlinear element and a low-pass filter in its loop. It is shown that by appropriate choices of these two components, the NPLL outperforms the standard PLL in three respects: (i) it has a large ...
