315MHz energy-efficient injection-locked OOK transmitter and 8.4µW power-gated receiver front-end for wireless ad hoc network in 40nm CMOS

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.
