Abstract
Provided is a hybrid envelope amplifier having improved efficiency, and more particularly, to an envelope amplifier using a dual switching amplifier and having improved efficiency in which power consumption is reduced by controlling a switching current of a switching region according to a magnitude of an envelope input signal, thereby improving efficiency compared to a conventional hybrid envelope amplifier. The envelope amplifier using a dual switching amplifier and having improved efficiency comprises a linear amplifier and a switching amplifier, wherein the switching amplifier includes two or more switching stages that are selectively operated according to a magnitude of an input signal.
