Abstract:
This paper describes a CMOS LNA for IEEE 802.11b front-end receiver for wireless LAN applications in a TSMC 0.18-μm process. The Front-end LNA specifications are derived from IEEE 802.11b standard. In this paper, we have designed a fully integrated CMOS Low Noise Amplifier (LNA) for IEEE 802.11b WLAN application by using CMOS 0.18μm technology for 2.4GHz frequency range with power supply of 1.8V. The circuit exhibits a good trade off among low noise, high gain and provides more reverse isolation which is crucial in LNA design. Complete simulation analysis of the circuit results in center frequency of 2.4GHz, with 37.6 dB voltage gain, 2.3 dB noise figure (NF), 1-dB compression point (dBm) of -17.13dBm, IIP3 (dBm) of -6.063dBm, 50Ω input impedance, 3dB power bandwidth of 450MHz,, 11.2dB power gain (S21), high reverse isolation (S12) < -60dB, Input return loss (S11) <-11dB, power dissipation of 2.7mW at 1.8V power supply.
