Abstract :
A fully integrated 4-channel UWB beam-former in 0.13μm CMOS uses a path-sharing true-time-delay architecture with 15ps resolution. The 3.1×3.2mm2 chip produces 11 different scanning angles within plusmn60deg with 10° spatial resolution for 25mm antenna spacing. The front-end achieves an NF of 2.9 to 4.8dB across 18GHz of BW with less than 5ps of group delay variation.
