A Fully-Integrated Direct-Conversion RF Front-End for Wi-Fi in 0.13µm CMOS

Zhengjia Lu, Jianmin Li, Zhicheng Wei

Abstract

A fully-integrated direct-conversion RF front-end for ISM band applications is presented. This RF front-end is designed and simulated with the 0.13µm cmrf8sf model in Cadence. The whole system simulation is performed and compared with proposed specifications. Wi-Fi, following IEEE802.11n standard, is a wireless communication protocol within the frequency range 2.4 GHz to 2.4835 GHz and is commonly used for wireless networking.  Wi-Fi can be used as a tool to access the internet by personal computers, video game consoles, mobile phones, MP3 players or personal digital assistants when within range of a wireless network connected to the Internet.  Wi-Fi also allows communications between computers directly. This is called the ad-hoc mode of Wi-Fi transmission. In this paper, this Wi-Fi system is supposed to be designed with low noise figure and low power consummation.
