2 cards from this section. Quick, good the night before a test.
What happens to current in the BJT under forward bias?
Think about how voltage affects current flow.
What is the primary characteristic of reverse bias?
Consider what happens at the junction when voltage is applied in this manner.
What is the effect of increasing the base-emitter voltage on the collector current in a BJT?
Reflect on the relationship between voltage and current in the active region.
True or False: The collector current in reverse bias is not influenced by the applied voltage.
Consider the stability of current flow against increasing reverse voltages.
If a transistor operates with a collector-emitter voltage of 10V and a base-emitter voltage of 0.7V, find the expected base current given that the base-emitter current is 1 mA and the base width is 0.2μm.
Explore how changing one parameter influences the others along with the supporting equations.
Design a BJT circuit to achieve maximum β while minimizing recombination losses. What factors must be considered?
Consider physical adjustments in design, such as narrowing the base width and adjusting doping levels.
