Abstract:
1. A circuit comprising an H-bridge, wherein the H-bridge comprises: a first pull-up switch configured to pull a first output node to a high voltage supply when the H-bridge is supplied with power and when the first pull-up switch is closed; a second pull-up switch configured to pull a second output node to the high voltage supply when the H-bridge is supplied with power and when the second pull-up switch is closed; a first pull-down switch configured to pull the first output node to a low voltage supply when the H-bridge is supplied with power and when the first pull-down switch is closed; a second pull-down switch configured to pull the second output node to the low voltage supply when the H-bridge is supplied with power and when the second pull-down switch is closed; an inductive impedance coupled between the first output node and the second output node; and means for maintaining at least one of the first and second output nodes at a temporally stable intermediate voltage while performing a switching operation.
