摘要： A driver circuit for driving a single conductor line that is coupled to a series of individually controlled circuit units each including a capacitor includes a power supply circuit for supplying a constant current to the single conductor line and a line driver supply circuit configured to modulate a digital information signal onto the constant current on the single conductor tine. The line driver further includes a signaling transistor structured to operate in a zero voltage switched mode at least part of the time, and a signaling inductor coupled between the single conductor line and the signaling transistor.

摘要： A direct current driver circuit for driving a modulated direct current is disclosed. The direct current driver circuit uses a switched capacitor network to keep the circuit operating within carefully prescribed voltage levels in order to reduce energy losses.
