Reduced-power dynamic data circuits with wide-band energy recovery are described herein. In one embodiment, a circuit system comprises at least one sub-circuit in which at least one of the sub-circuits includes a capacitive output node that is driven between low and high states in a random manner for a time period and an inductive circuit path coupled to the capacitive output node. The inductive circuit path includes a transistor switch and an inductor connected in series to discharge and recharge the output node to a bias supply. A pulse generator circuit generates a pulse width that corresponds to a timing for driving the output node.
