    Abstract: An electronic device including a shielding structure is provided. The electronic device includes a housing, a first board disposed in an inner space of the housing and including a first electrical element and a first ground layer, a second board disposed in the inner space to be spaced apart from the first board and including a second electrical element, and an interposer disposed between the first board and the second board so as to electrically connect the first board and the second board to each other. The second board includes a first surface facing the first board, a second surface facing away from the first surface, insulating layers disposed between the first surface and the second surface, first slits formed at a predetermined interval in a first conductive area disposed in a first insulating layer among the insulating layers, and second slits formed at a predetermined interval in a second conductive area disposed in a second insulating layer between the first insulating layer and the second surface. The first slits are disposed at a position where the plurality of first slits do not overlap the plurality of second slits in case the second board is viewed from above.

    Abstract: A digital radio frequency (RF) transmitter including processing circuitry configured to generate first through third pattern signals based on a pattern of an inphase (I)-quadrature (Q) binary data pair and a pattern of an inverted I-Q binary data pair, the first through third pattern signals having a same pattern and different phases, and a switched-capacitor digital-to-analog converter (SC-DAC) configured to remove an n-th harmonic component of an RF analog signal by amplifying the first through third pattern signals to have a certain magnitude ratio and synthesizing the amplified first through third pattern signals into the RF analog signal, where “n” is an integer of at least 3, may be provided.

    Abstract: An electronic device and noise canceling method thereof is provided. The electronic device may include a housing; at least one output circuit arranged inside the housing and configured to generate a first signal; an opening formed on one side of the housing; a hole connected to the opening; a receptacle arranged inside the hole, and configured to receive an external connector, and electrically connected to the at least one output circuit; at least one sensor arranged within a predetermined proximity range to at least one of the opening and the receptacle; and a control circuit electrically connected electrically to the at least one output circuit, the receptacle, and the at least one sensor, wherein the control circuit is configured to detect the external connector approaching to at least one of the opening and the receptacle using the at least one sensor, to generate a second signal upon detection of the approaching external connector, and to control the at least one output circuit to change the first signal at least partly based on the second signal.
