Abstract

In this paper, a fully integrated CMOS receiver front-end for 2.4-GHz Band IEEE 802.15.4 standard in a 0.18-μm CMOS technology is presented. It is comprised of a low-power CMOS LNA including a common-gate stage with modified input matching and active balanced down-conversion mixer which uses the current bleeding technique and an extra LC filter to improve the noise figure (NF) and conversion gain (CG). The proposed front-end achieved a CG of 28.7 dB and NF of 7 dB. The total DC power consumption of this front-end is 14.4 mW from a 1.8 V supply voltage.
