Abstract
This article presents a millimeter-wave (mm-wave)
transmitter (TX) front-end employing a new inverse outphasing
architecture with current-mode power amplifiers (PAs). This
study on the conventional outphasing operation reveals its strong
dependence on its voltage-mode driving source assumption and
thus exhibits major limitations at mm-wave, since efficient and
linear mm-wave PAs often behave as current sources. To address
this challenge, we propose a current-mode inverse outphasing
architecture th
