DPLL

This repository displays a detailed construct of a Digital Phase Locked Loop made in Cadence Virtuoso.

Elements involved in the Circuit

• Phase Frequency Detector
• Charge Pump
• Voltage Controlled Oscillator
• Divide by N (In this case, N = 3)
• Loop Filter

The use of DPLL

Phase locked loops play a significant role in the modern-day circuits. They are used to demodulate the amplitude and frequency modulated signals, synchronize clocks, recover small signals from noise, and they are used in devices such as dual-tone multiple frequency decoders and modems.
