Abstract

This paper presents the design of a dual-band low noise amplifier (LNA) with a single input differential outputs of 5.2 GHz and 2.4GHz band with 0.18?m CMOS technology. In order to achieve the goal of expanding the availability of telecommunication system, this LNA is designed as a dual-band operation by using a band pass filter and a notch filter simultaneously [1]. Moreover, by introducing the CG (common gate)-CS (common source) topology [2], we can obtain the output phase differs by 0 and 180 degrees. This will reduce the connection loss to the mixer developed in the previous study [3]. In this paper, simulation results of gain, noise figure and output phase difference are shown, and a chip layout is shown. The proposed LNA has a gain of 16.5 dB and 11.1 dB at 2.4 GHz and 5.2 GHz, a noise figure of 3.1 dB and 3.7 dB, and the phase difference is less than 0.32 degrees.
