Abstract:
1. A circuit comprising a first pulse-generator subcircuit and a first power-supply subcircuit configured to supply a first DC potential to the first pulse-generator subcircuit, wherein the first pulse-generator subcircuit comprises: a first transmission-line segment comprising first and second conductors and having a first length, wherein the first conductor is coupled to the power-supply subcircuit; a first terminating resistor coupled to a first end of the second conductor of the first transmission-line segment; first and second switches, controlled by first and second timing signals, respectively, and configured to selectively and independently connect respective first and second ends of the first conductor to a second DC potential; a delay-line subcircuit comprising a second transmission-line segment having third and fourth conductors, wherein the third conductor couples the second end of the second conductor to a first output node; and a second pulse-generator subcircuit and an inverting delay-line subcircuit coupling the second pulse-generator subcircuit to the first output node, wherein the delay-line subcircuit's fourth conductor is connected to an end closest to the first pulse-generator subcircuit and is connected to a first selectively operable isolating switch at the opposing end, and wherein the inverting delay-line subcircuit comprises a third transmission-line segment having fifth and sixth conductors, wherein the fifth conductor couples an output of the second pulse-generator subcircuit to a second selectively operable isolating switch, and the sixth conductor is connected to an end closest to the first pulse-generator subcircuit and connected to the first output node at the fourth conductor's opposing end.
