Current Amplifier Circuit Using Transistor. These circuits produce outputs that vary or are linear. Active 2 years 2 months ago.
Amplifier circuits can be thought of as control circuits. A current amplifier can be realized using transistors the schematic of a current amplifier circuit using transistors is shown in the figure below. By driving the collector current ic proportional to the base current ib.
These circuits produce outputs that vary or are linear.
Amplifier devices such as transistors or ics can also be used to switch current on or off depending on how they are biased in the circuit. These circuits produce outputs that vary or are linear. The photodiode absorbs energy from light and releases electrons thereby acting as an input current source. By driving the collector current ic proportional to the base current ib.
