Abstract: A logic device with low electromagnetic interference. The logic device includes a digital logic gate, a voltage-limited circuit and a current-limited circuit. The digital logic gate provides a corresponding digital logic function. The voltage-limited circuit is connected to the digital logic gate in order to provide a fixed voltage to the digital logic gate to thus reduce an output voltage swing of the digital logic gate. The current-limited circuit is connected to the digital logic gate in order to provide a fixed current to the digital logic gate to thus reduce a transient current of the digital logic gate. Accordingly, an electromagnetic interface (EMI) caused by switching of the digital logic gate is reduced with the reduced output voltage swing and transient current.

Abstract: A radio frequency (RF) signal transmitting device adapted to transmit signals between a computer and a plurality of wireless peripheral equipment is developed. The RF signal transmitting device includes a plurality of RF signal transmitters and an RF signal receiver. The RF signal transmitters are electrically connected to the plurality of wireless peripheral equipment, respectively, and each is provided for modulating an output signal therefrom into an RF signal with a specific carrier frequency and transmitting the RF signal. The RF signal receiver is electrically connected to the computer for synchronously receiving the RF signals from the RF signal transmitters and converting each of the RF signals to an operating signal to operate the computer.
