Abstract

A fully integrated 2 2 CMOS transceiver at 60 GHz with energy harvesting capabili ty in the transmitter mode and on-chip dipole antennas is demonstrated. The radio supports on-off-keying (OOK) modulation and a programmable data rate of 38 to 2450 Mb/s at a BER of less than 5 10 . The power consumption of the transmitter scales with data rate from 100 W to 6.3 mW at 5 cm range and from 260 Wt o1 1 . 9m Wa t 10 cm range. This yields an en ergy efﬁciency of 2.6 pJ/b at 5 cm and 4.9 pJ/b at 10cm. The energy harvesting circuits operate at 2.45 GHz with an average efﬁciency of 33%. The harvesting antenna and its matchin g components are off-chip. The complete transceiver including the energy harvesting block and on-chip antennas occupies 1.62 mm in 40 nm CMOS.
