Abstract: An display driving circuit including a buffer write controller transmitting a different image frame to a first buffer or a second buffer, a buffer scan controller scanning an image frame stored in the first buffer or the second buffer on the basis of a predetermined cycle, a write signal detector controlling the buffer write controller such that a second image frame is transmitted to the second buffer after a first image frame is transmitted to the first buffer, and a scan buffer switching controller receiving an EOF (End of Frame) command indicating the completion of transmission of the first image frame to the first buffer and controlling the buffer scan controller such that the first image frame stored in the first buffer is scanned after the image frame previously stored in the second buffer is scanned.

Abstract: In an operating method of a radio frequency integrated circuit (RFIC) including a transmission circuit and a reception circuit, the operating method includes receiving, from a modem, first information for setting transmission power of the transmission circuit or second information about a blocker which is a frequency signal unused by the RFIC, obtaining an allowable value of phase noise of a local oscillator included in the transmission circuit, using the first information, obtaining an allowable value of phase noise of a local oscillator included in the reception circuit, using the second information, determining a level of a driving voltage, using the obtained allowable values of the phase noises, and providing the driving voltage to the local oscillators.
