Abstract :
In this paper, a CMOS implementation of phased-array receiver front-end, based on a widely tunable QVCO is presented. Each path achieves 30dB of gain and a minimum NF of 7.1dB, yielding a system NF of 4.1dB. The overall current draw is 54mA from a 1.2V supply. Additionally, a calibration procedure to mitigate the analog impairments imposed by the proposed implementation is demonstrated.
