A 65nm CMOS 4-element Sub-34mW/element 60GHz phased-array transceiver

The 60GHz band has received significant attention as an enabler for multi-Gb/s wireless communication. Practical mm-Wave systems will require relatively large phased arrays in order to robustly overcome path-loss and fading issues. Despite significant progress, CMOS implementations of 60GHz phased arrays have so far been area and power hungry. This paper therefore presents a 60GHz 4-element 65nm CMOS phased-array transceiver consuming <;34mW/element (including LO synthesis and distribution) that utilizes baseband (BB) phase shifting and holistic impedance optimization.
