Abstract

A CMOS power amplifier for IMT-2000 is designed with 0.25-${\mu}m$ CMOS technology. This amplifier circuits consist of two cascode stages. Used cascode structure has good reverse isolation. These amplifier circuits consist of two stages which are driver stage and power amplification stage. The designed power amplifier is simulated with ADS using 0.25-${\mu}m$ CMOS library at 3.3 V power supply. Simulation results indicate that the amplifier has a PAE of 39 % and power gain of 24 dBm at 1.95 GHz.
