A 6.0-GHz Low Noise Amplifier and A 6.0-GHz Class-E Power Amplifier

-Devices using 0.18mum CMOS process are used to design radio frequency amplifiers, a 6.0-GHz low noise amplifier (LNA) and an 6.0-GHz Class-E power amplifier. The LNA, with input power P in =10.38mW, input voltage V dd =1.5V, and input current I d =6.92mA, provides a forward gain S 21 =32.135 dB with a Noise Figure as low as 1.0dB. In addition, a 6.0 GHz E-class amplifier, with input voltage V dd =1.5V, provides a forward gain S 21 =22.374dB with P out =7.136 dBm and power added efficiency PAE = 76.1%. Both amplifiers are to be checked on the architecture and linearity for comparison. Class-E power amplifiers with different center frequencies are to be presented and their corresponding S21's are checked, too.
