A 20–23GHz Coupled Oscillators Array in 65nm CMOS for HDR 60GHz beamforming applications

A Coupled Oscillator Array (COA) based on 4 differential LC Voltage Controlled Oscillators (VCO) with 21,5GHz central frequency and 15% locking range is presented. It achieves a maximum phase-shift of 100° which makes it suitable for 60GHz WirelessHD™ and WiGig applications with beamforming. The COA is implemented in a 65nm bulk CMOS process and dissipates 24mW from a 1.2 V supply.
