Abstract
Embodiments of the present disclosure may provide a method of calibrating an isolator system. The method may comprise the steps of driving a common signal to a pair of input terminals of the isolator system; measuring differences in signals at output terminals of the isolator system; and varying impedance of impedance elements connected between the output terminals and a center-tap terminal of the isolator system until a mismatch at the output terminals is minimized.
