摘要

电压缩放是当今用于控制soc的静态和有功功率的旋钮之一。SoC核心电源电压可根据性能需求自适应缩放。但它也需要维护外部电子芯片接口协议,该协议可能在不同的电压水平下运行。芯片接口需要在自适应缩放核心电压和固定10电源电压下可靠地工作。在10个电路中,电压电平移位器用于在两个电压域之间进行通信。本文分析了传统电压移电平器的性能,介绍了一种新型的高性能移电平器,该移电平器在自适应电压标度下具有更强的鲁棒性。

A Robust Level-Shifter Design for Adaptive Voltage Scaling
Voltage scaling is one of the knobs that is used today to control both static and the active power for SoCs. The SoC core supply voltage is scaled adaptively based on the performance needs. But it is also required to maintain the external electrical chip interface protocol, which may run at a different voltage level. The chip interfaces need to operate reliably under adaptively scaling core voltage and fixed 10 supply voltage. Within the 10 circuits, voltage level shifters are used to communicate between two voltage domains. This paper examines the performance of a conventional voltage level shifter and describes a novel high performance level shifter that is more robust under adapting voltage scaling.
