  • Patent number: 10128326
    Abstract: A resistor comprises a substrate, an upper ohmic region disposed on a selective one of an upper surface and a lower surface of the substrate and a lower ohmic region disposed on the other one of the upper surface and the lower surface of the substrate. An upper metal conducting layer overlies on the substrate and the upper ohmic region, and a lower metal conducting layer overlies on the lower ohmic region. When the upper and lower metal conducting layers are electrified, the upper ohmic region and the lower ohmic region are electrically connected, and a contact interface between the substrate and the upper metal conducting layer forms an enlarged depletion region to block electrical conduction therebetween. As a result, a resistance value of the resistor is increased when an applied voltage on the resistor is increased.

  • Patent number: 10129973
    Abstract: A voltage divider circuit assembly includes resistors, an external electrostatic shield, and internal electrostatic shield(s). The resistors are in series with each other between input terminals that receive an input voltage. An external resistor is disposed between sensing terminals that conduct an output voltage that is the input voltage divided by the resistors in the series. The external shield is conductively coupled with the series of the resistors with the external resistor disposed outside of the external shield and the other resistor(s) inside the external shield. The internal shield(s) are conductively coupled with the resistors and disposed inside the external shield. A first internal resistor is disposed inside the external shield and outside of the internal shield(s). One or more remaining resistors are inside the internal shield(s). The shields divide parasitic capacitances to enable the measurement of dynamically changing high voltage input signals.
