Abstract :
An integrated 2×2 OOK transceiver at 60GHz with energy harvesting transmitter (TX) and TX power scalable with data rate is demonstrated. The TX power scales from 100μW to 6.3mW at 5cm range and from 260μW to 11.9mW at 10cm range, supporting 38-to-2450Mb/s with a BER<;5×10-4. Energy is harvested at 2.45GHz with an average efficiency of 33%. It occupies 1.62mm2 in 40nm CMOS and the TX energy efficiency is 4.9pJ/b and 2.6pJ/b at 10cm and 5cm respectively.
