Abstract
Serial arranged circuits allow multiple different circuit nodes to receive power with a single conductor line carrying current. Data can be transmitted to the serially arranged circuit nodes by modulating the current on the single conductor line. However, switching transistors to modulate current can consume energy. To reduce the switching losses, a double ended driver circuit is disclosed. The doubled ended driver circuit includes switching capacitors and inductors at both ends of a serial string of circuit nodes.
