Abstract: According to an embodiment of the disclosure, an electronic device may include a sensor that is connected to a plurality of displays, and a processor that is connected to the sensor and the plurality of displays, where, when information indicating that an error occurs in a first display among the plurality of displays is obtained from the sensor, the processor may output first information to be output through the first display through a display having higher priority among remaining displays. Various other embodiments are also possible which are known from the specification.

Abstract: Disclosed is a quadrature VCO (voltage controlled oscillator) which comprises a first delay cell including a first switching transistor and a second switching transistor, the first delay cell outputting first and second in-phase signals with different phases; and a second delay cell including a third switching transistor and a fourth switching transistor, the second delay cell outputting first and second quadrature-phase signals with different phases. The first and second quadrature-phase signals are applied to back gates of the first and second switching transistors, and the first and second in-phase signals are applied to back gates of the fourth and third switching transistors.
