This paper presents a Split Inductor Based Dynamic Ramp Generator with Variable Offset for high-performance buck converters. The proposed ramp generator employs an adaptive current starving mechanism to drive the ramp signal, enabling the output voltage to respond instantly to load changes and significantly reducing overshoot, undershoot, and response time. The high-level architecture of the buck converter, compensator, and stability response are derived and demonstrated. The transistor-level implementation of the proposed circuit, including the comparator, is also presented. The proposed ramp generator was implemented in a 90nm technology and extensively tested through simulation and experimentation. Simulation results show that the Dynamic Ramp Generator with Variable Offset based buck converter outperforms state-of-the-art topologies in terms of phase behavior and other key performance metrics. Under a 1.8V to 1.2V voltage conversion, the proposed converter exhibits excellent transient response, with a load transient change from 35mA to 500mA resulting in minimal overshoot and undershoot. The experimental results validate the practicality and effectiveness of the proposed control scheme in fulfilling the requirements of assured stability, reduced undershoot, overshoot, and transient response. The proposed approach represents a significant advancement in buck converter design, offering a robust and efficient solution for high-performance power conversion applications.
