Abstract
This Project presents a comprehensive comparison and performance analysis of ring oscillators (ROs) and current-starved voltage-controlled oscillators (VCOs) implemented using 45-nm CMOS technology. Both ROs and current-starved VCOs are fundamental building blocks in modern integrated circuits, particularly in frequency synthesis and clock generation applications. Understanding their performance characteristics and trade-offs is crucial for optimizing VLSI circuit designs. This Project begins with a detailed overview of ROs and current-starved VCOs, highlighting their operating principles and design considerations in 45-nm CMOS technology. Key performance metrics, including oscillation frequency, power consumption, are identified for comparison. Simulation experiments are conducted using Tanner Tool and transistor models to evaluate the performance of ROs and current-starved VCOs under various operating conditions. The results of the comparative analysis are presented and analyzed, revealing the strengths and weaknesses of each oscillator architecture. The findings indicate that while ROs offer simplicity and low power consumption, current- starved VCOs provide superior frequency stability. Trade-offs between these metrics are discussed, providing insights into the selection of the most suitable oscillator architecture for specific VLSI applications. This Project contributes to the understanding of ROs and current-starved VCOs in 45-nm CMOS technology, enabling designers to make informed decisions when integrating these oscillators into VLSI circuits. Future research directions for further optimization and performance enhancement are also suggested based on the observed trends and challenges
