A PVT-variation tolerant fully integrated 60 GHz transceiver for IEEE 802.11ad

Abstract

A PVT tolerant fully integrated 60 GHz transceiver for IEEE 802.11ad is presented. By introducing a newly proposed self-sensing LDO, the transceiver adjusts bias currents and the LDO output voltage for the PA to minimize the output power variation while relaxing the hot carrier injection (HCI) degradation. The measurement shows excellent robustness against PVT variations, demonstrating only 5 dB output power variation over -20 °C to 85 °C across process corners.
