Abstract
A 4-antenna path beamforming analog baseband section implemented in 40 nm low power CMOS for use in a phased-array 60 GHz receiver is presented. The circuit combines fourth-order filtering with a cutoff frequency of 1 GHz, beamforming and variable gain between 10.6 dB and 30 dB. Output IP3 above 10 dBm and output noise below 4.2 mVrms over the whole gain range yield an SFDR larger than 31.2 dB, which is sufficient for QAM16 modulation according to IEEE 802.15.3c. The circuit consumes less than 42 mW.Keywords
