reverse bias การใช้

• For a figure describing forward and reverse bias, see semiconductor diodes.
• The latter dominates under forward bias while the former dominates under reverse bias.
• In transistor-selected arrays, only the selected bit lines contribute reverse bias leakage current.
• We run into suspicion, possibly reverse bias, and the syndrome of the closed mouth.
• Forward bias ( positive to positive ), reverse bias ( negative to negative ).
• That very small current is the source of the leakage current under reverse bias.
• *I'm may perhaps not be popular for saying this, but there's reverse bias also.
• A photodiode is designed to operate in reverse bias.
• This change in channel strength by application of reverse bias is called the'body effect '.
• Pinch-off occurs at a particular reverse bias ( V GS ) of the gate-source junction.
• MQW devices must be operated at high reverse bias fields to achieve good contrast ratios.
• In this diode the voltage remains relatively constant ( independent of current ) when it is connected in reverse bias.
• Under reverse bias, the diode ordinarily does not conduct ( save a small dark current or I s leakage ).
• When the reverse bias breakdown voltage is exceeded, a conventional diode is subject to high current due to avalanche breakdown.
• In either formulation, r _ O varies with DC reverse bias V _ { CB }, as is observed in practice.
• The small current that flows under high reverse bias is then the result of thermal generation of electron-hole pairs in the layer.
• When this energy level is higher than that of the electrons, no tunnelling will occur, and the diode is in reverse bias.
• The collector depletion region also increases under reverse bias, more than does that of the base, because the collector is less heavily doped.
• This depletion region is much larger than in a PN diode, and almost constant-size, independent of the reverse bias applied to the diode.
• There is also a recovery concern where the current will not decrease immediately when it is switched from forward bias to reverse bias.
