  • METHOD AND RELATED CIRCUITRY FOR BUFFERING OUTPUT SIGNALS OF A CHIP WITH EVEN NUMBER DRIVING CIRCUITS
    Publication number: 20040027176
    Abstract: A method and related circuitry for driving output signals of a chip is disclosed. The method includes driving output signals with an even number of inverter driving circuits, and keeping an equivalent load of each inverter of the driving circuits substantially identical by keeping impedances of each driving circuit substantially identical.

  • Signal transmission device for minimizing simultaneous switching noise in integrated circuit chip and the signal transmission method thereof
    Patent number: 6624764
    Abstract: A signal transmission device which transmits n-bit parallel digital signals through an I/O driver to minimize simultaneous switching noise in an integrated circuit chip is proposed. The signal transmission device includes an encoder coupled to the I/O driver which receives the n-bit parallel digital signals and performs an encoding operation to the n-bit parallel digital signals to provide encoded m-bit parallel digital signals for the I/O driver, where m>n and the encoding operation is performed by a rule that the number of logic-1 bits of the encoded m-bit parallel digital signals is maintained at p and the number of logic-0 bits of the encoded m-bit parallel digital signals is maintained at (m−p), where Cpm>2n and m>p>0, and a decoder coupled to the I/O driver which receives the encoded m-bit parallel digital signals and performs a decoding operation to the encoded m-bit parallel digital signals to restore the n-bit parallel digital signals.
