摘要：

A 2.4GHz CMOS differential common-gate low noise amplifier (CGLNA) is presented. It utilizes two on-chip differential inductors instead of four on-chip single-ended inductors in traditional designs, resulting in significantly reduced die area. Furthermore, two noise reduction techniques, i.e. capacitive cross-coupling and MOSFET channel length optimization, are discussed. A prototype was fabricated in a 0.18 mu m RF CMOS process, and was packaged for testing. The measurement results are in agreement with circuit simulations.
