Patent ID: 8803593

Claim:
A method comprising: setting voltage levels at a plurality of remote nodes with respect to a reference voltage during a voltage setting period, wherein each of the plurality of remote nodes is coupled to a common node through at least one resistor and is configured to be between the at least one resistor and at least one capacitor, wherein the setting comprises: isolating the common node and the plurality of remote nodes from at least one voltage source; evaluating a voltage level at the isolated common node for a first time period, wherein the first time period is sufficient for charge redistribution that enables the voltage level at the common node to more accurately reflect the voltage levels at the plurality of remote nodes; and removing charge from the at least one capacitor through the at least one resistor for a second time period based on the evaluating; wherein the evaluating and removing is repeated as long as the sum of the repeated first and second time periods is less than the voltage setting period.
