mm-Wave Front-End Design for Phased-Array Systems

In the previous chapters, a monolithic mm-wave sensor network was introduced. An on-chip wireless power receiver with an ultra-low-power receiver and transmitter front-end was presented. In this chapter, the base-station for monolithic sensor networks with phased-array architecture is analyzed and the key circuits are developed. By using a phased-array architecture, the base-station can achieve better sensitivity for the receiver part, and can also increase the transferred power density at the sensor node location for the transmitter part.
