Objective

The main objective of this project is to design an effective performance PLL using novel structure of PFD using Dynamic inverter and frequency divider structures in the the design of final PLL circuit.

Abstract

This paper introduces a modified design of CMOS dynamic Phase Frequency Detector (PFD). The proposed PFD circuit (PPFD) is designed, simulated and the results obtained are analyzed. In order to reduce dead zone, internal signal routing is used in the PPFD circuit. To extend, Phase Locked Loop (PLL) is designed and it is verified with Frequency Divider (FD) circuit. There is a decrease in area of the PLL circuit with 55 transistors and dissipates power of 89.2 pW for 1.8 V power supply. The pre-layout simulation result shows that the PPFD circuit has an elimination of a dead zone. Further, it works with the high speed and reduced power operated in the reference frequency.

Key words:-PFD, Dead Zone, VCO, Power, PLL
