A 1-V, 6-mA, 3-6 GHz broadband 0.18-μm cmos low-noise amplifier for UWB receiver

A 3-6 GHz broadband CMOS single-ended LNA fabricated with the 0.18 μm 1P6M process for UWB and WLAN receiver is presented. Due to its noncascode circuit architecture, the proposed LNA can operate under IV supply voltage and 6mA current consumption. In the UWB low band (3.1-5.15 GHz), the broadband LNA exhibit a gain of 11.7-13.7dB, noise figure less than 4.9 dB and input return loss better than 13.2 dB, respectively. From 5-6 GHz range (covering Hiperlan, 802.11a, and MBOA group B), the LNA exhibit a gain of 12.4-12.7 dB, noise figure less than 5.5 dB and input return loss better than 15.7 dB, respectively. The input P_IdB and IIP3 are -20 dBm and -10.9 dBm, respectively.
