The point on the load line where it intersects the collector current axis is referred to as " saturation point ".
22.
In active mode, the ratio of the collector current to the base current is called the " DC current gain ".
23.
The Early effect ( base-width modulation ) in Q1 will force its collector current to be slightly higher than that of Q2.
24.
Transistor Q3 is represented by its low-frequency hybrid-pi model with a current controlled dependent current source for the collector current.
25.
The process of obtaining a certain DC collector current at a certain DC collector voltage by setting up the operating point is called biasing.
26.
A lower base-resistor voltage drop reduces the base current, which results in less collector current because I c = ? I B.
27.
The ratio of these currents varies depending on the type of transistor, and even for a particular type, varies depending on the collector current.
28.
In this region, I c = ?I b where Ic is collector current and Ib is base current, following linear relation y = mx.
29.
The biasing base currents needed to evoke the quiescent collector currents usually come from the ground, pass through the input sources and enter the bases.
30.
Some basic circuits can be designed by assuming that the emitter base voltage is approximately constant, and that collector current is beta times the base current.
