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： In order to control individual circuit nodes coupled to a common serial line, each of the different circuit nodes must be assigned a locally unique address. However, mass manufactured electronics are manufactured as identical electronic devices. Thus, several techniques are presented for assigning unique addresses to identical electronic devices coupled to a common serial line. One set of techniques uses a local sensor that is stimulated in order to specify a single device on the serial line. Another set of techniques measures a pulse presented onto the common serial by a circuit node to determine its relative position on the serial line.

摘要： 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.
