Both MOSFETs and IGBTs require sufficient charge deposited into their gate junctions, whilst maintaining a minimum gate threshold voltage in order to remain in conduction.
Once the dc voltage decreases to the minimum threshold value, that is, over the boundary in Eq. (14), DVR will stop compensating process to avoid harmonic pollution of load voltage.
To assess the occurrence of output responses produced by an input spike, the 18 ms following each input spike was searched for either a 1 in the binarized output trace (indicating a postsynaptic action potential) or an EPSP in the original voltage trace (with a minimum threshold of 1 mV).
When the externally applied voltage to the TS device is higher than the threshold voltage (i.e., the minimum voltage to turn on the TS device), the resistance of TS device is abruptly decreased, so that the applied drain voltage is dropped in the channel, again.
A two dimensional Poisson's equation has been solved with parabolic potential approximation to establish the expressions of front and back channel surface potential distribution and the threshold voltage has been derived from the minima of such obtained potential.
Including the effect of PVT variations for determining minimum leakage vector is crucial because leakage currents have an exponential dependence on power supply, threshold voltage and temperature.
As revealed, once the programming voltage increases beyond the threshold voltage, the cell resistance starts to drop due to the crystallization of AST alloy and then reaches a minimum, which is corresponding to the set resistance.
As revealed, once the programing voltage increases beyond the threshold voltage, the cell resistance starts to drop due to the crystallization of GST alloy and then reaches a minimum, which is corresponding to the set resistance.
Samples that represent "healthy" patients yielded voltages under the transistor threshold voltage in all tested devices.
There is no minimum threshold in the Netherlands.
