Voltage Amplifier Transistor Circuit Diagram Provided. We only limit the sum of the feedback. In the above circuit diagram we have made a voltage divider circuit using resistor r1 and r2 of 4 7k and 1 5k respectively.

A small amount of current or voltage can control a larger amount of voltage or current. These circuits produce outputs that vary or are linear. So for example if we input 1v into the circuit we can get 10v as output if we set the circuit for a gain of 10.

Block diagram of an amplifier.

Voltage amplifiers many times are built with op amp. When the input ac voltage 0 v the collector current is found to be 1 0 ma. Let us consider a voltage divider biasing circuit which is commonly known as a single stage transistor amplifier circuit. These circuits produce outputs that vary or are linear.
