Abstract: A power supply modulator includes: a linear regulator; a switching regulator; and a mode-based connection circuit. The mode-based connection circuit includes a coupling circuit configured to drop an output signal of the linear regulator by a target coupling voltage in an envelope tracking (ET) modulation mode; and a coupling voltage management circuit configured to monitor a coupling voltage of the coupling circuit in another modulation mode, and selectively apply a voltage to the coupling voltage based on a monitoring result such that the coupling voltage is maintained at the target coupling voltage.

Abstract: A supply modulator includes: a voltage generator including output terminals respectively outputting voltages having different levels, and configured to select, in response to a selection control signal corresponding to an envelope signal, at least one of the voltages as a selection supply voltage and to generate the selection supply voltage by performing DC-DC conversion on a power supply voltage; and a switch unit configured to connect an output terminal through which the selection supply voltage is output to a power amplifier, in response to a connection control signal corresponding to the envelope signal.

Abstract: Provided are photographing apparatuses and methods of controlling the same. The photographing apparatuses may set an auto-focusing (AF) region according to a touch, a drag, and a touch release on a touchscreen, thereby making it possible to prevent the AF region from being easily shifted by an unintended touch of a user.

Abstract: A photographing apparatus and a method of controlling the same are provided. The photographing apparatus includes a display unit which displays an image, an input unit via which a command is input, and a control unit which controls the display unit to display icons representing changed settings of the photographing apparatus on a predetermined region of the display unit when settings of the photographing apparatus are changed according to an input command that is input via the input unit. Accordingly, the photographing apparatus is capable of providing a user with a changed function setting among function settings.
