Phase detector - Wikipedia
A phase detector or phase comparator is a frequency mixer, analog multiplier or logic circuit that generates a signal which represents the difference in phase between two signal inputs. The phase detector is an essential element of the phase-locked loop (PLL).
6.6: Phase Detector - Engineering LibreTexts
May 22, 2022 · The block diagram of a phase detector is shown in Figure \(\PageIndex{1}\)(a) with the output \(y(t)\) related to the difference of the phase of the input signals \(x(t)\) and \(w(t)\). A square wave detector is based on a logic circuit producing a signal that is averaged (or integrated) over time. An example is the XOR gate shown in Figure ...
Phase Detector - an overview | ScienceDirect Topics
A phase detector is a mixer-like circuit that puts out a signal that is proportional to the phase difference between two input signals of the same frequency. From: Electronics Explained, 2010. Add to Mendeley. Chapters and Articles. You might find these chapters and articles relevant to this topic. Low-noise oscillator design.
Analog Phase Detector Circuit Diagram
Oct 9, 2017 · The analog phase detector circuit diagram is fairly straightforward. It contains a few transistors, resistors, and diodes, arranged in a classic differential amplifier configuration. This allows the circuit to accurately measure the difference in phase between the two signals.

Chapter Abstract: This chapter describes the operation principles and circuits of phase detectors and charge pumps. Non‐memory phase detectors including multiplier, XOR gate, flip‐flop, sample‐and‐hold, and sub‐sampling phase detectors are briefly discussed.
HOW PHASE DETECTORS WORK. The basic concept upon which phase detec-tion rests is that the application of two iden-tical frequency, constant amplitude signals to a mixer results in a dc output which is pro-portional to the phase difference between the two signals.
