Abstract

This paper presents a wide band LNA for the IEEE 802.11 WLAN. The LNA uses two feedback paths to enhance linearity and in-band gain ripple. The -3 dB bandwidth is 4 GHz with center frequency of 4.7 GHz. The current reuse technique is utilized to reduce the power consumption and the noise figure (NF). Post-Layout simulation results demonstrate that the achievable input third-order intercept point (IIP3) is -2 dBm, and the NF equals 3.07 dB. Using a 0.18 μm CMOS process, the power consumption is 8.8 mW under a supply voltage of 1.8 V. The total area including pads is 1.48 mm×1.51 mm.
