In this paper, a CMOS low-noise amplifier (LNA) with a new input matching topology has been proposed, analyzed and measured. The input matching network is designed through the technique of capacitive feedback matching network. The proposed LNA which is implemented in a 0.18-mu m 1P6M CMOS technology is operated at the frequency of 12.8 GHz. It has a gain S21 of 13.2 dB, a noise figure (NF) of 4.57 dB and an NF(min) of 4.46 dB. The reverse isolation S12 of the LNA can achieve -40dB and the input and output return losses are better than -11 dB. The input 1-dB compression point is -11 dB m and IIP3 is -0.5 dB m. This LNA drains 10 mA from the supply voltage of 1 V. (C) 2008 Published by Elsevier B.V.

This letter describes the analysis and measurement of a complementary metal-oxide semiconductor (CMOS) quadrature-balanced current-mode mixer with a 90 degrees branch-line hybrid coupler and self-switching current-mode devices. The proposed mixer, using 0.13 mu m 1P8M CMOS technology, can downconvert a 60 GHz RF signal to a 2 GHz intermediate frequency (IF) signal, with a local-oscillator power of 0 dBm at 58 GHz. In the design, the mixer had a single-end conversion gain of 1 dB and an input-referred I dB compression point of 2 dBm. The LO-RF isolation of the mixer can achieve -37 dB while using 3 mA from a supply voltage of 1.2 V.
