Abstract: An electronic device with a reduced noise may include a printed circuit board and a signal creating unit mounted on the printed circuit board and configured to create at least one signal. The electronic device may also include at least one power via configured to connect a power terminal of the signal creating unit with a main power line disposed in the printed circuit board. The electronic device further includes at least one ground via configured to connect a ground terminal of the signal creating unit with a main ground disposed in the printed circuit board. In this electronic device, the ground via is disposed in parallel with the power via.
