Semiconductor Fundamentals Unit 6 – Transistor Load Lines and Gain
The above table shows the base-emitter junction and base-collector junction voltage bias
necessary for the transistor to be in the saturation, active, or cutoff states.
A dc load line is a plot of the collector current (IC) versus the collector-emitter voltage (VCE).
The active region is between the saturation point and cutoff point.
NEW TERMS AND WORDS
load line - a plot of collector current versus collector voltage used to determine the best transistor
operating point.
saturation point - the operating point at which maximum collector current is flowing in a
forward biased transistor.
cutoff point - the operating point of a reverse biased transistor (not conducting).
quiescent point - the dc operating point of a transistor equal to about half of the supply voltage.
