WebThe common-emitter, forward-current, amplification factor is better known as _____. ac β. In a small-signal transistor, the typical range of the parameter β is _____. large and in the range of about 50 to 400. A BJT has measured dc current values of IB = 0.1 mA and IC = 8.0 mA. When IB is varied by 100 μA, IC changes by 10 mA. What is the ... Webto forward bias the parasitic BJT, it will turn on, leading to catastrophic failure. There have been many advances in MOSFET design technology targeted at minimizing the base resistance R B to prevent the bipola r turn-on. However, no MOSFET is totally immune to latch-up. Junction temperature plays an important role in triggering the failure.
