CMOS Phase Detector and Phase-Frequency Detector Power and Delay Estimation Using Nano Dimensional MOS Transistors

A Nano-dimensional transistor phase detector circuit is covered in detail in this article. To demonstrate this, a standard phase-frequency detection circuit is built. Tanner SPICE simulation software is used to simulate the circuit designs. The phase detector circuit's power dissipation, transistor delay, and power-delay product have all been calculated for gate lengths as small as 16 nm and as long as 22 nm. A VDD of 0.5 V-1.2 V also a PMOS/NMOS aspect ratio of 1 to 5 were used in the power and speed study. The phase-frequency detector's power, gate delay, and PDP were all measured at 150 nm channel length. It's now feasible to create a VLSI circuit with fast speed andlow power consumption thanks to recent findings.
