This talk presents the design and implementation of a sub-mm-Wave fully integrated signal generator array. It is based on a harmonic oscillator designed in a standard 65-nm digital CMOS technology. The talk will cover the design methodology, the electromagnetic modeling and simulations. The harmonic oscillator concept is further elaborated to build a unique beamforming technique called Y-vector network. This approach has been recently developed by the High-Speed Electronics Laboratory (HSEL) at UCLA. It will be also presented. This beamforming technique features minimized chip area and DC power consumption. It requires no traditional adjustable phase shifter at multi-channel front end which usually suffer from high insertion loss at these frequencies. A compact 1x4 Beam Steering Phased Array (BSPA) is validated at 0.55THz with about ±30° steering angle range.
