Abstract

Embodiments provide a charge pump circuit which produces a bias voltage that is applied to a transient suppression device used to clamp both positive and negative transients on signal lines. The bias voltage can be set to a level that is above the sum of a DC voltage differential between positive and negative signal lines and the maximum signal voltage.
