A 2.4GHz LNA Design for 802.11 WLAN Applications

Abstract

Over the last decade, the front-end design in the RF transceiver has become a major role and is greatly enhancing the data rate of the transceiver. RF design is augmenting due to the fast-growing wireless communications markets. For a motivated potential design required data rate, low latency, gain, stability, and linearity considerations must converge. Being different wings of technology, the RF design, and its implementation is a difficult task even though such long research on RF and Microwave theory. CMOS technology has made unique considerable progress since its development in the mid-sixties. Over ten years after the fact, during the seventies, the first industrial products were made available in the market. Today, CMOS technology is a widely accepted standard for innovation and the versatile market of computerized ICs. The essential ambition of RF communication is to transmit and receive information through analog RF front ends. LNAs are found in an environment to amplify weak signals which are operating in numerous operational frequencies such as Bluetooth devices, cordless telephones, some radio equipment, and wireless keyboards. In this paper, with associated trade-offs in RF design, a systematic method for designing an LNA block with accurate MOS transistor sizing and computation of precise passive components is presented.
