Logic device with low EMI |
摘要 |
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.
