Nanowatt Receiver for High-Data-Rate Advanced Internet of Things and Microwave Applications: A novel exploitation of body bias and stage ratios in a Dickson detector

Abstract

This work presents a single-chip nanowatt receiver with three main design blocks: the input matching network (IMN), the envelope detector (ED), and the comparator. A center-symmetric pseudobalun Dickson detector with body-bias control is proposed to enhance the receiver performance in terms of sensitivity and low dc power consumption at higher data rates. The receiver supports ON–OFF keying (OOK)-modulated signals in the 2.4-GHz Industry, Science, Medicine (ISM) band at data rates up to 400 Kb/s, achieves a measured latency of only ${3}{.}{87}\hspace{0.33em}\mathit{\mu}\hspace{0.06em}{\text{s}}{,}$ and consumes only 11.7 nW of power. The receiver is implemented in a 40-nm CMOS process and operates from 0.8- and 0.5-V supply voltages.
