A low-power 71GHz-band CMOS transceiver module with on-board antenna for multi-Gbps wireless interconnect

Abstract

Fully integrated millimeter-wave transceiver ICs using 65nm CMOS technology and on-board antenna for highspeed/short-range wireless communication system are described. To realize high-speed and low power consumption for a mobile application, a simple transceiver architecture with non-coherent amplitude shift keying (ASK) modulation method is adopted. The transceiver ICs are flip-chip bonded on boards and connected with on-board antenna for a simple and low cost transceiver system. The developed transceiver system module demonstrates 5Gbps/3.8Gbps at wireless communication range of 5mm/10mm and power consumption of 79.6mW with a carrier frequency of 71GHz. To our best knowledge, this is the first report of a millimeter-wave, above 60GHz, CMOS transceiver module with on-board antenna for a highspeed/short-range wireless communication system.

23Gbps 9.4pJ/bit 80/100GHz band CMOS transceiver with on-board antenna for short-range communication

“…The developed 80GHz/100GHz-band transceiver modules demonstrate 15.4Gbps/7.6Gbps at wireless Figure 2 shows the transmitter circuit diagrams of (a) 80GHz-band and (b) 100GHz-band. To achieve low power consumption, a push-push VCO, generating a second harmonic signal, is applied to the 100GHz-band instead of a fundamental oscillator adapted to the 80GHz-band [5]. A push-push VCO can generate larger output power with lower power consumption than that of a fundamental VCO especially at as high frequency as 100GHz-band [3].…”
