A Ku-band build-in-self-test (BIST) chip in CMOS is presented for RF beamforming arrays in 5G mobile communication systems. Since the beamforming array in 5G systems has hundreds of antenna elements, the BIST circuits must be incorporated in the RF chains to be able to accurately detect and control the phase and amplitude of the signal such that the… CONTINUE READING
