Abstract
A method for controlling ground plane voltages by locally, at one or more discrete points on the working ground reference, sensing a voltage difference between a working ground reference and an isolated ground reference, generating a voltage compensation signal based on the voltage difference, and driving the working ground reference with the voltage compensation signal to reduce the voltage difference.
