A miniaturized 2.4-GHz CMOS low-noise amplifier using a gate-source coupling technique

Abstract

In this study, we proposed a miniaturization technique for a differential RF CMOS low‐noise amplifier (LNA). The inductors of the input matching network and for the source degeneration are magnetically coupled to minimize the area for the inductors. By adapting this technique in a CMOS LNA, the parasitic resistance induced by both the input and the source degeneration inductors is reduced, improving the noise figure and gain of the amplifier. To verify the feasibility of the proposed technique, we designed the 2.4‐GHz differential LNA using 0.13‐µm RF CMOS technology. © 2014 Wiley Periodicals, Inc.

Compact and high‐linearity 77 GHz CMOS receiver front‐end for automotive radar

“…However, a CMOS Rx front-end suffers several drawbacks in terms of noise and linearity, which limit the detectable range and sensitivity of the radar systems [4]. Many circuit structures have been proposed to improve the performance of CMOS Rx for 77 GHz application [5][6][7][8][9][10][11][12][13][14][15][16], but the linearity of CMOS Rx is still limited and many of them occupy a large silicon area. In order to meet the different requirements of automotive radar supporting both short-and longrange communications, the Rx front-end requires high linearity.…”
