ABSTRACT:
First and second complementary voltage signals are operatively coupled across a series circuit comprising first and second sense resistors and a circuit element therebetween. A DC bias current in the series circuit is substantially nulled, and an output signal responsive to the self-impedance of the circuit element is generated responsive at least one of a voltage across the first sense resistor and a voltage across the second sense resistor.
