Answers
A phase detector or phase comparator is a frequency mixer, analog multiplier or logic circuit that generates a voltage signal which represents the difference in phase between two signal inputs. It is an essential element of the phase-locked loop (PLL).

Answer:
The phase comparator in a PLL circuit is generally used to provide the comparison between phases of two signals and is also used to generate voltage in accordance with the phase difference.
Explanation:
A phase-locked loop (PLL) is a digital circuit with a voltage or voltage-pushed oscillator that continuously adjusts to suit the frequency of an entering signal. PLLs are used to generate, stabilize, modulate, demodulate, clear out out or get better a signal from a "noisy" communications channel wherein records has been interrupted.
PLLs are broadly utilized in wi-fi or radio frequency (RF) applications, together with Wi-Fi routers, broadcast radios, walkie-talkie radios, televisions and cellular phones.
At its simplest, a phase-locked loop is a closed-loop comments manipulate circuit this is each frequency- and phase-sensitive. A PLL isn't a single component, however a machine that includes each analog and digital components -- interconnected in a "negative comments" configuration. Consider it analogous to an intricate operational amp (op amp)-primarily based totally amplifier circuit.
