High voltage subnanosecond breakdown
IEEE Transactions on Plasma Science, 1998Present-day ultra-wideband radiation sources produce Megavolt pulses at hundreds of picosecond (ps) risetimes. Empirical data on the breakdown characteristics for dielectric media at these short time lengths and high voltages are either extremely limited or nonexistent.

Breakdown voltage of high-voltage bipolar transistors
Solid-State Electronics, 1991Abstract An empirical expression for open-base bulk breakdown voltage of an epitaxial n+pn−n+ bipolar transistor as a function of collector doping density and common-emitter current gain is useful in the design of the collector region of the transistor.

LTCC Breakdown Voltage Investigation
Additional Conferences (Device Packaging, HiTEC, HiTEN, and CICMT), 2016Abstract High voltage properties of the LTCC (Low Temperature Co-Fired Ceramics) cofired ceramic tape are presented. Chauvin Arnoux C.A. 6555 insulation tester is used to measure the leakage current and the resistance. Measurement is possible up to 15 kV. The DuPont 951 test structures are manufactured.

Effect of Ultraviolet on Breakdown Voltage
Transactions of the American Institute of Electrical Engineers, 1935The effect of ultraviolet light upon the breakdown voltage of sphere gaps subjected to impulse voltages is considered in this paper. It is shown that, especially for the smaller gaps and corresponding lower voltages, more accurate voltage measurements result when ultraviolet light is used.

Voltage breakdown characteristics of microwave antennas
IRE International Convention Record, 1959At low pressures, antennas are susceptible to voltage breakdown. In the case of missiles, for example, there are indications that very low power is sufficient to initiate and maintain breakdown. Since it is essential that the system performance is not interrupted for high-altitude operation, an experimental investigation has been made to study the ...

Goal-Oriented Adaptivity for Voltage Breakdown Prediction
IEEE Transactions on Magnetics, 2018An innovative approach has been recently proposed for the voltage breakdown prediction in high-voltage systems, insulated by large vacuum gaps. This approach is based on complementary geometric formulations for electrostatics coupled to the analytical solution of the equations of motion for charged particles.

A breakdown voltage doubler for high voltage swing drivers
Proceedings of the IEEE 2004 Custom Integrated Circuits Conference (IEEE Cat. No.04CH37571), 2004A novel breakdown voltage (BV) doubler is introduced that makes it possible to generate high output voltage swings using transistors with low breakdown voltages. The timing analysis of the stage is used to optimize its dynamic response. A 10 Gb/s optical modulator driver with a differential output voltage swing of 8 V on a 50 /spl Omega/ load was ...

Resistor networks with distributed breakdown voltages
Physical Review A, 1991As a primitive model for structural breakdown in elastic media, we analyze the failure of random resistor-fuse networks with various distributions of properties. We show that variations in breakdown voltage have a more significant effect than variations in resistance values. This is analogous to the fiuid-displacement problem [D.Y.C. Chan, B. D. Hughes,

Avalanche breakdown voltage of In0.53Ga0.47As
Journal of Applied Physics, 2002Avalanche breakdown voltages were determined for a series of In0.53Ga0.47As p-i-n diodes with i-region thicknesses ranging from 0.4 to 4.79 μm using measurements of reverse dark current and phase-sensitive photomultiplication. Despite its narrower bandgap In0.53Ga0.47As is found to have a very similar breakdown voltage to GaAs.
