Abstract :
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.
