| Summary: | 碩士 === 國立交通大學 === 電子工程系所 === 95 === In this thesis, a dual-gain mode design of a direct-conversion CMOS RF LNA for IEEE 802.16e (WiMAX) applications is presented. Two gain modes with one switch stage are designed in the purposed LNA to enlarge the dynamic range. It needs only one common input matching network for different gain modes. Multiple Gated Transistors topology is integrated for linearity enhancement. The circuit is fabricated in 0.13�慆 CMOS process, and it is designed for operation frequency of 2.3 to 2.7 GHz. A behavior model of the circuit is constructed to facilitate the design cycle.
