BASIC TRANSISTOR AMPLIFIER - amplifies by producing a large change in
collector current for a small change in base current. This action results in
voltage amplification because the load resistor placed in series with the
collector reacts to these large changes in collector current that, in turn, results
in large variations in the output voltage.
THREE TYPES OF BIAS - used to properly bias a transistor are base-current bias
(fixed bias), self-bias, and combination bias. Combination bias is the one most
widely used because it improves circuit stability and at the same time
overcomes some of the disadvantages of base-current bias and self-bias.
