摘要

实现更快的动态响应是未来微处理器稳压器(VR)面临的重大挑战之一。众所周知，为了获得更快的动态响应，系统带宽需要更高，但系统带宽通常受到开关频率附近相移的限制。本文总结了现有的相移理论和为实现更快的瞬态响应所做的努力。分析了一种采用双边缘控制器的高带宽设计。带宽设计为大于开关频率的一半。然后用硬件对设计进行验证。

Analysis and Design of the Dual Edge Controller for the Fast Transient Voltage Regulator

Achieving faster dynamic response is one of the big challenges for the future microprocessor voltage regulators (VR). It is well known that the system bandwidth needs to be higher to get a faster dynamic response but the system bandwidth is usually limited by the phase shift near the switching frequency. In this paper, the existing theories for this phase shift and efforts to achieve a faster transient response are summarized. A higher bandwidth design using a dual edge controller is analyzed. The bandwidth is designed to be larger than one half of the switching frequency. The design is then verified with the hardware.
