Abstract :
An RF-path 60-GHz band 4-element array using proposed phase-oversampling vector modulation is implemented in 65-nm CMOS. Digitally controlled semi-lookup table method is proposed to compensate for non-idealities in circuits, antenna array, and interfaces. Accurate and high resolution control on the gain and phase is demonstrated. The receiver features an NF of 5.6 dB and 3.5° phase resolution at a backoff of 3 dB. It dissipates 178 mW from I-V supply and obtains 18.5 dB gain for each channel.
