摘要

本文分别通过改进数字低差(DLDO)和开关电容稳压器(SCVR)的控制器，改进了一种基于数字低差(DLDO)和开关电容稳压器(SCVR)的混合型全集成稳压器。该控制器经过改进，在DLDO模式下实现了可调的电压下降响应和更高的功率效率。增加了自适应宽度方案，提高了SCVR模式下的功率效率。因此，在DLDO模式下实现了可调的电压下降响应和3%的峰值效率上升。采用自适应宽度方案，在SCVR模式下，总功率效率平均提高3%，峰值效率提高6%。

An Improved Design of Hybrid Integrated Voltage Regulator Based on DLDO and SCVR

This paper improves a hybrid fully integrated voltage regulator based on digital low-dropout (DLDO) and switched-capacitor voltage regulator (SCVR) by improving the controllers of DLDO and SCVR, respectively. The controller is improved to achieve tunable voltage droop response and larger power efficiency during DLDO mode. Adaptive width scheme is added to increase the power efficiency during SCVR mode. As a result, tunable voltage droop response and 3% peak efficiency rising is achieved during DLDO mode. Using adaptive width scheme, the overall power efficiency is increased by 3% on average and the peak efficiency is increased by 6% during SCVR mode.
