This paper presents a wideband low-complexity multi-stream beamforming transceiver (TRX) based on multiple local-oscillator (multi-LO) phase-shifting fully-connected (FC) architecture for MIMO communication. In supporting the same beams, the proposed architecture halves the complexity of the FC combiners as well as the ADCs/DACs overhead. Meanwhile, the FC combining network of each stream is imple...Show More
A wideband CMOS low-noise amplifier (LNA) with multiple resonant frequencies is demonstrated in this article. A common source (CS) with inductive degeneration topology is widely employed in LNA circuit design to decouple the input impedance from the noise figure (NF). Since CS with inductive degeneration topology only achieves a single resonant frequency, it generally has narrow bandwidth performa...Show More
