Abstract :
This paper presents the design and fabrication of an LNA and a mixer for a multiband UWB wireless receiver using distributed circuit topologies. First, the design of a 3-stage CMOS distributed LNA circuit consisting of three cascode cells is introduced. Next, the design of a 2-stage CMOS distributed mixer consisting of two single-balanced cells is presented. The LNA and mixer circuits are separately designed and fabricated in a 0.18 μm CMOS process. The LNA circuit achieves a 2.9 dB NF over the entire 7.5 GHz BW. It exhibits a forward gain of 8 dB, and an IIP3 of -3.4 dBm. The mixer circuit is capable of covering the RF and LO frequencies over a wide range of frequencies from 3.1-8.72 GHz.
