Abstract

Cognitive Radios are expected to provide in the near future an alternative solution for the heavy usage of the spectrum, especially for commercial purposes. Wideband front-end circuits, as low-noise amplifiers (LNAs), are then an alternative. This paper presents a new CMOS topology capable of simultaneous noise canceling and broadband input power matching for the range of 50 MHz to 5 GHz with flat power gain of 12 dB, noise figure of 1.5 dB to 2.5 dB while consuming 15 mW of power. It is designed on a 0.13 μm RFCMOS technology with no inductors, making the circuit very compact.
