A 60-GHz fully integrated CMOS sub-harmonic RF receiver with mm-wave on-chip AMC-antenna/balun-filter and on-wafer wireless transmission test

Abstract

This paper presents a first reported 60-GHz fully integrated 90-nm CMOS RF sub-harmonic receiver with an artificial magnetic conductor (AMC) on-chip antenna and a balun-filter. The on-chip antenna with AMC structure can reduce the substrate loss and increase the antenna radiation efficiency and power gain. The on-chip balun-filter combines the integrated design of the balun and RF bandpass filter (BPF) which can reduce the circuit size and the insertion loss. In order to mitigate the DC offset, the sub-harmonic receiver is adopted in this work. The probe-station based on-wafer wireless transmission test at a distance of R=1 m is conducted. The measurement show that the receiving conversion gain CG <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">ant+Rx</inf> and OIP3 of the integrated RF receiver (with the AMC on-chip antenna and balun-filter) are 16 dB and 3 dBm, respectively, at 60 GHz. The study will be very useful for the design of a fully integrated mm-wave CMOS single-chip radio.
