A 0.13μm CMOS fully differential receiver with on-chip baluns for 60GHz broadband wireless communications

This paper presents a fully differential receiver with on-chip baluns for 60 GHz broadband wireless applications. This design consists of on-chip baluns, gm-boosted current-reuse low-noise amplifier (LNA), sub-harmonic dual-gate down conversion mixer, second IF mixer and baseband gain stage. Fully differential circuit technique is adopted to obtain good common mode performance. The gm-boosted current-reuse differential LNA mitigates the noise, gain, robustness, stability, and integration issues associated with previous solutions. The sub-harmonic dual-gate down conversion mixer prevents the issue of the third harmonic of the LO as well. The measured conversion gain and input P1dB of the proposed receiver are 30 dB and -27 dBm, respectively. The measured noise figure at 100 MHz baseband output is around 10 dB. The proposed 60 GHz receiver dissipates 44 mW with a 1.2 V supply voltage. The fully differential receiver with the on-chip baluns is implemented in a standard 0.13 mum 1P8M+ RF CMOS technology.
