Abstract

A power amplifier(PA) has been designed for 900 MHz-band applications. The PA consists of a single-ended CMOS amplifier which has $0.18{\mu}m{\times}64{\times}6$ gate width. The PA has been designed using $0.18{\mu}m$ CMOS process. At 900 MHz, the PA exhibit an output power of 20.8 dBm and a power-added efficiency(PAE) of 58.4 % with 22.2 dB power gain.
