Concurrent multiband low-noise amplifiers-theory, design, and applications

The concept of concurrent multiband low-noise-amplifiers (LNAs) is introduced. A systematic way to design concurrent multiband integrated LNAs in general is developed. Applications of concurrent multiband LNAs in concurrent multiband receivers together with receiver architecture are discussed. Experimental results of a dual-band LNA implemented in a 0.35-mum CMOS technology as a demonstration of the concept and theory is presented.
