摘要

本文设计了一种工作在亚阈值区域的准延迟不敏感双轨(QDI-DR)异步FIR低通滤波器。该滤波器采用0.13μm标准CMOS技术，能够在各种电压、温度和工艺下工作。布局后仿真表明，该设计以2.5kHz的速度实现了170mV的最低工作电压。最节能的点发生在250mV，功率延迟积(PDP)为2.53pJ。

A Quasi-Delay-Insensitive Dual-Rail low-pass filter working in subthreshold region

In this paper, we present a design of Quasi-Delay-Insensitive Dual-Rail (QDI-DR) asynchronous FIR low-pass filter working in subthreshold region. The filter is implemented in 0.13μm standard CMOS technology and is able to operate with variations of voltages, temperatures and processes. Postlayout simulation shows the design achieves the lowest operating voltage of 170mV with a speed of 2.5kHz. The most energy-efficient point occurs at 250mV with a Power-Delay Product (PDP) of 2.53pJ.
