Sagi Sreevibhu | Teendra Pavan Kumar | Varikallu Harish Kumar | Shaik Riyazuddien


Abstract: The performance of Ring Oscillator (CMOS RO) and Current Starved Voltage Controlled Oscillator (CS - VCO) in 90nm CMOS technology is thoroughly analyzed in this paper. The study involves a detailed examination of transient responses, parametric characteristics, and key performance metrics, such as delay, frequency, and power consumption. Our primary focus is on identifying optimal configurations for enhanced efficiency, with particular emphasis on understanding the impact of Inverter Stages on RO performance. Throughout systematic simulation and analysis, we aim to reduce power consumption while optimizing various parameters. Practical layouts for ROs and CS - VCOs are also designed to facilitate real - world implementation. The findings from this research contribute to the advancement of oscillator design in semiconductor technology, offering valuable insights for future circuit optimization endeavors. Power efficiency is paramount across all electronic systems, but it becomes especially critical in RF applications powered by batteries. These systems demand meticulous attention to detail to minimize power dissipation and extend operational life. In conclusion, we underscore the importance of power reduction as a key objective, and our analysis and conclusions will be based on its impact on overall efficiency and performance.
