A 60GHz 16Gb/s 16QAM low-power direct-conversion transceiver using capacitive cross-coupling neutralization in 65 nm CMOS

Abstract

This paper presents a 16QAM direct-conversion transceiver in 65nm CMOS, which is capable of 60-GHz wireless standards. The capacitive cross-coupling neutralization contributes a high common-mode rejection and a high reverse isolation, and a fully-balanced mixer can improve the error vector magnitude due to the reduced local leakage. The maximum data rates with an antenna built in a package are 10Gb/s in QPSK mode and 16Gb/s in 16QAM mode and the transmitter and the receiver consume 181mW and 138 mW, respectively.
