Design of Frequency Divider (FD/2 and FD 2/3) Circuits for a Phase Locked Loop

Abstract

This paper reports on three design of Frequency Divider (FD/2) and Frequency Divider (FD 2/3) circuits. Tanner EDA tool developed on 130nm CMOS technology with a voltage supply of 1.3 V is used to build, model, and compare all circuits. For the FD/2 circuit, E-TSPC Pass Transistor logic uses 1.77 µW, whereas TSPC logic consumes 5.57 µW for the FD 2/3 circuit. It implies that the TSPC logic is the best solution since it meets the speed and power consumption requirements.
