A wideband beamformer for a phased-array 60GHz receiver in 40nm digital CMOS

A programmable analog baseband beamformer for a 4-antenna 60 GHz phased-array receiver is implemented in 40 nm digital CMOS. It is based on current amplifiers employing shunt feedback. The phase shifter resolution is better than 20°, with a bandwidth of 1.7 GHz, power consumption of 35 mW, input-ref...

Description
Summary:A programmable analog baseband beamformer for a 4-antenna 60 GHz phased-array receiver is implemented in 40 nm digital CMOS. It is based on current amplifiers employing shunt feedback. The phase shifter resolution is better than 20°, with a bandwidth of 1.7 GHz, power consumption of 35 mW, input-referred noise current of 170 nA rms and output IP3 of -6 dBV.
