BJT Structure
This is how many semiconductor layers a BJT has.
What is 3?
This is the process of applying a DC voltage to set the characteristics of a BJT.
What is Biasing?
This graph shows the relationship between VCE and IC.
What is the BJT characteristic curve?
This is the mode of operation when the transistor allows no current to flow.
What is cutoff?
This is the smallest current in a BJT.
What is IB?
The region between the emitter and collector is known as this.
What is the base?
This is the majority carrier in a NPN BJT.
What are electrons?
What is IB?
This is the mode of operation when a BJT lets the maximum current through.
What is Saturation?
This value represents the maximum current that can flow through a BJT.
What is IC(sat)?
This is the number of diode junctions in a BJT.
What is 2?
This is the formula relating the three currents in a BJT.
What is IE = IC + IB
This is the point on the characteristic curve where VCE = VCC
What is Cutoff?
This is the mode of operation when a transistor lets less than the maximum but more than zero (more accurately leakage) current to flow.
What is active or linear?
This value represents the voltage dropped from the Collector to the emitter.
What is VCE?
This type of BJT is designed with a p-type base sandwiched between two n-type regions.
What is an NPN transistor?
This is the only region in an NPN BJT which has holes as the majority carrier.
What is the Base?
The maximum collector current IC(sat) is determined by this component.
What is RC?
This is what a transistor is being used as when operated in either saturation or cutoff.
What is a switch?
This value represents the DC current gain of a BJT.
What is BetaDC?
This layer is heavily doped to provide a large number of charge carriers.
What is the Emitter?
The BE junction in BJT must have this kind of bias to operate in the linear region.
What is forward-bias?
This is the name of the line connecting the saturation and cutoff point.
What is the DC load line?
This is what a transistor is being used as when operating in the linear/active region.
What is an amplifier?
This value is the h-parameter you will look up in a datasheet to find BetaDC.
What is hFE?
