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

-Devices using 0.18μm 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.
