  • Control circuit for an output driving stage of an integrated circuit
    Patent number: 6567318
    Abstract: An impedance control circuit controls the impedance of an integrated output driving stage. The integrated output driving stage includes at least one enabling/disabling transistor and at least one driving transistor. The impedance control circuit includes a variable impedance circuit having an impedance that varies with the temperature in correlation with the impedance of the output driving stage. A control circuit is connected to the variable impedance circuit for generating at least one enabling/disabling signal for the at least one enabling/disabling transistor based upon a control signal correlated to the impedance of the variable impedance circuit. The impedance control circuit also includes a current generating circuit for applying to the variable impedance circuit a current which remains substantially stable as the temperature varies.
