Abstract
This paper presents the design of a low-power wake-up receiver (WuRX). The proposed WuRX composed of an active envelope detector with high input impedance to support high passive gain, a self-biased high-gain IF-Amplifier, a dynamic comparator, and a proposed level-Tracking calibration circuit that mitigates circuit drift. This OOK-modulated WuRX is implemented in a 90-nm CMOS process and operates at the 400-MHz MICS band. Operated from a 0.5-V supply, this WuRX consumes 1.79-W. It supports 250-kbps data rate and achieves-40-dBm sensitivity. ? 2020 IEEE.
