6.2 A Phased-Array-Inspired Broadband RF Signal Processor for 2-to-32GHz Spectrum Sensing
Abstract
This paper presents a phased-array-inspired RF signal processor for ultra-broadband spectrum sensing. The proposed architecture exploits the bandpass response resulting from the constructive and destructive interference of a programmable dispersion-engineered array, implemented with broadband true-time delay lines and programmable phase shifters. The proposed design is fabricated in a 22 nm FDX process, achieving a measured scanning range of 2 to 32 GHz with a power consumption of 101 mW.
