—An RF-path 60-GHz band 4-element array using proposed phase-oversampling vector modulation is implemented in 65-nm CMOS. Digitally controlled semi-lookup table method is proposed to compensate for non-idealities in circuits, antenna array, and interfaces. Accurate and high resolution control on the gain and phase is demonstrated. The receiver features an(More)
A mmWave communication system is equipped with a large number of antennas so as to achieve higher directional gains. Phased array antenna with beam switching is widely-used to minimize the cost of the hardware implementation for the 60 GHz system. An array with beam switching is allowed only to steer at a fixed number of pre-defined angles called beams.(More)
In this paper, we propose a new capacitive boosted buffer technique that can be used in high speed interconnect for ultra-dynamic voltage scaling (UDVS) application with the process variation effect mitigated. The circuit is simple and fully compatible with digital CMOS technology. Implemented in a standard 0.18 μm CMOS technology, the circuit is shown(More)
