Abstract
A supply modulator includes a multi-level voltage generator configured to generate a plurality of power voltages having different voltage levels; a switch array including a plurality of switches respectively corresponding to the plurality of power voltages, and outputting one of the plurality of power voltages by activating connection of one of the plurality of switches; and a switch controller configured to control connection of each of the plurality of switches and activate connection of at least one third switch distinguished from a first switch and a second switch in response to receiving a level control signal switching the connection from the first switch to the second switch during a time period corresponding to a frequency to be attenuated between disconnecting the first switch and connecting the second switch.
