Abstract
In this paper, a fully integrated Class-E amplifier IC using back-gate voltage injection is designed, fabricated and fully evaluated in 0.18-µm CMOS technology. The body effect allows to achieve high efficiency under low supply voltage by efficiently controlling threshold voltage and on-resistance of switching transistor, simultaneously. The proposed amplifier IC has exhibited an output power of 11.0 dBm and a PAE of 30.5 % at 1-V supply voltage for 2.5 GHz applications.
