A Fully Synthesizable Distributed and Scalable All-Digital LDO in 10nm CMOS

📋 论文概要

本文提出了一种全数字、可综合、分布式且可扩展的低压差稳压器（LDO），采用10nm CMOS工艺实现。该设计无需定制通信或模拟电压传感器，通过分散的LDO单元共享供电网络，改善了本地IR压降和瞬态响应。

💡 主要创新点

• 首次实现了完全可综合的分布式全数字LDO，所有控制逻辑均为数字标准单元，便于在不同工艺间移植。
• 提出了一种无需全局控制器或邻居间定制通信的分布式架构，利用共享供电网络实现点负载调节。
• 通过全数字方式生成内部参考电压，消除了模拟电压传感器和专用参考电压路由的需求。

regulation for digital IP blocks. A distributed LDO architecture, where a number of dispersed LDO units supply a single domain with shared power delivery network (PDN), has been recently proposed for point-of-load regulation improving both local IR-drop and transient droop response across the IP domain [1-3]. However, previous distributed LDOs used custom communication between a global controller and local distributed LDO controllers [1], custom communication between neighboring LDO controllers [2], and/or analog voltage sensors with associated shared VREF generation and routing [1-3]. This paper presents a fully synthesizable, Distributed, and scalable all-Digital LDO (D-DLDO) voltage regulator (Fig. 25.1.1) with the following salient features: (1) fast single-cycle voltage monitoring using
