摘要：

In the last years we have assisted to a great development of wireless receivers working in narrow frequency bands. Nowadays, this development goes towards more flexible wireless receivers which accommodate different wireless applications wide-band and multi-band receivers. In this paper we study techniques suitable for the design of dual-band CMOS low noise amplifiers (LNA), based on cascode switching and inductor magnetic coupling. Two LNA topologies were evaluated and implemented in a 0.35 mu m CMOS process. A proof of concept, a prototype of a proposed dual-band CMOS LNA was designed to work simultaneously at 0.9 GHz and 1.8 GHz. It uses a voltage supply of 2.4 V consuming 4.8 mA.
