| Abstract: | Radio frequency amplifier which made in a SOC is an important unit of the RF front end.After analyzing and comparing the characteristic of various power amplifiers,the circuit brings up with a design of a 2.4GHz CMOS fully integrated linear power amplifier(PA) based on a SMIC 0.35-μm CMOS technology for WLAN system.The power amplifier which designed in this paper used the differential two-stage structure.The drive stage is made up of cascade class-A topology,a "big" MOSFET is used in the class-A output stage.The circuit performed simulation of the PA by Candence with the SMIC 0.35-μm RF CMOS model.According to the simulation results,with a supply voltage of 3.3V,the CMOS RFIC PA works steadily,the PA provides a 25dBm output power at 1dB compression point,the out power of the PA reaches to 25.22dBm when the input power of is 0dBm. |
