Abstract
Abstract A method and apparatus for altering the apparent electrical characteristic of a distributed electrical component in an integrated circuit is disclosed. In one form a distributed load resistor is sunk into a parallel distributed guard resistor. The mutual distributed capacitance between the distributed load resistor and the parallel distributed guard resistor is substantially greater than the distributed capacitance between the distributed load resistor and any other electrical component. A follower circuit for driving the voltage across the parallel distributed guard resistor by the voltage across the distributed load resistor is provided.
