Abstract: This paper introduces a novel technique for addressing frequency boost jitter in Voltage Controlled Ring Oscillators (VCROs) through advanced control strategies and design enhancements. By integrating a hybrid phase-locked loop (PLL) architecture with adaptive filtering, the method dynamically adjusts the control voltage to stabilize the oscillator frequency. The approach incorporates a real-time feedback system that continuously monitors and compensates for phase noise variations, leading to a marked reduction in jitter. Validation through extensive simulations and practical experiments reveals up to a 50% improvement in frequency stability over traditional VCRO designs. Additionally, the proposed design ensures low power consumption and a compact form factor, making it suitable for diverse applications including wireless communication systems and high-speed data converters. This research provides an effective jitter reduction solution that can be customized for different operational settings and process variations, emphasizing the value of such advancements in enhancing electronic circuit reliability and performance. The findings advocate for ongoing innovation in VCRO design and optimization techniques. Index Terms—Frequency stability, Adaptive filtering, Oscillator design, Jitter reduction
