Abstract
These teachings provide for detecting an offset voltage corresponding to a circuit element having an input and an output. (The approaches taught herein will accommodate detecting that offset voltage at either the input and/or the output as desired.) Upon detecting the offset voltage a switch that connects the input of the circuit element to ground automatically closes to thereby ground the input. That switch remains open in the absence of detecting an offset voltage.
