| 20110266885 | Bipolar Pulse Generators With Voltage Multiplication - A bipolar pulse generator includes two, two-conductor transmission lines coupled together with a load positioned between the two transmission lines. Each conductor of a transmission line we define as a segment. Two segments of one transmission line are charged and switchably coupled to two segments of the other transmission line to produce a bipolar pulse on the matched load. This bipolar pulse generator may be implemented in a flat or a folded design. The generator may include two transmission line structures coupled together with a load positioned between each transmission line structures. The first transmission line structure may include a stepped transmission line and an embedded transmission line segment. A switch may be coupled between the embedded transmission line segment and another segment of the transmission line structure. During operation, the first transmission line structure may be charged to a potential with the switch in the open position and, when the switch is closed, the charge on the first transmission line structure together with the second transmission line structure generates a bipolar pulse on the matched load. | 11-03-2011 |
| 20110032022 | DIFFERENTIAL SWITCH WITH OFF-STATE ISOLATION ENHANCEMENT - Techniques are disclosed for reducing off-state leakage current in a differential switching device. The techniques can be embodied, for example, in a method that includes receiving a differential input signal at a differential input of each of a primary switch and a dummy switch. In an enabled-state of the device, the method further includes passing the differential input signal to a differential output of the primary switch. In a disabled-state of the device, the method further includes canceling off-state leakage current at the differential output of the primary switch, by virtue of the dummy switch having its differential output reverse-coupled to the differential output of the primary switch. The method may further include preventing the dummy switch from passing signals other than off-state leakage signals. The techniques can be embodied, for instance, in a switching device. | 02-10-2011 |
