  • Noise reduction for output drivers
    Patent number: 4862018
    Abstract: High current capacity output drivers for digital devices have output noise reduced and more quickly achieve stability by the insertion of resistance in series with inherent, parasitic inductance. The resistance may be one or more fixed resistances formed in the same circuit as the drivers. The resistance may also include sensor devices that selectively increase the resistance of the output drivers in accordance with the voltage produced by the parasitic inductors. Both fixed resistances and sensor devices may be used together.
