Design and Simulation of 1.9GHz Phase-Locked Loop Clock Generator with 45nm Generic CMOS (For High speed Serial Link Applications)

The demand for high-speed serial links (HSSLs) is increasing rapidly due to the need for faster, more robust, and more power-efficient inter-IC communication. HSSLs are used in a variety of applications, including data centers, networking, and high-performance computing. A key component of an HSSL is the clock generator, which provides a low-jitter, low-phase-noise clock signal that is essential for reliable data transmission. This paper presents the design and simulation of a phase-locked loop (PLL) based clock generator for HSSL applications. The PLL is designed to generate a 1.9 GHz clock signal with a considerably low phase noise and low jitter. The design is implemented in a 45nm Generic CMOS process and is simulated using Cadence Virtuoso tools. The simulation results show that the PLL meets the desired specifications and is suitable for HSSL applications.
