Concurrent Multiband Low-Noise Amplifiers—Theory, Design, and Applications

نویسنده

  • Hossein Hashemi
چکیده

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 0.35m CMOS technology as a demonstration of the concept and theory is presented.

RF Analog Circuit Design with Scaled CMOS Devices

Because of the prospect of low cost and high integration of scaled CMOS, much effort is being focused on its use for Radio-Frequency (RF) communication circuits. Low Noise Amplifiers (LNA) are essential building blocks for the design of communication systems, and some applications would benefit from the use of low cost CMOS transistor technology to build the LNA. MOS transistors are typically c...

Comparison between single band and concurrent multi-band linear power amplifiers

Currently the multiple wireless data transmission technologies have been commercially implemented, such as long-term evolution (LTE), Wi-Fi, and Bluetooth. There is a keen requirement to combine the power amplifiers for those technologies into a single one which can amplifies concurrent multi-band signals. On the physically layer, there are two popular architectures, namely parallel single-band...

24.6 Noise Cancelling in Wideband CMOS LNAs

Wideband low-noise amplifiers (LNAs) are used in receivers processing several signal channels such as TV cable modem, multiband mobile terminals and base stations. High sensitivity applications require sufficient gain, good isolation and a noise figure (NF=10·log10(F)) below 3dB over a wide frequency range. Moreover, source impedance matching (i.e. ZIN=RS) is usually wanted to limit reflections...
