315MHz Energy-Efficient Injection-Locked OOK Transmitter
and 8.4µW Power-Gated Receiver Front-End
for Wireless Ad Hoc Network in 40nm CMOS

 

Abstract

A 315MHz injection-locked OOK transmitter and a power-gated receiver front-end for wireless ad hoc network are developed in 40nm CMOS. The developed injection-locked frequency multiplier for carrier generation by edge combining achieves 11µW power consumption at 315MHz. The proposed power-gated low noise amplifier with current second-reuse technique achieves the lowest power consumption of 8.4µW with 7.9dB noise figure and 20.5dB gain in state-of-the-art designs.
