Simple two transistor amplifier

- a simple design for a two transistor amplifier with feedback

This electronic circuit design shows a simple two transistor amplifier with feedback. It offers a reasonably high impedance while providing a low output impedance. It is an ideal transistor amplifier circuit for applications where a higher level of gain is required than that which would be provided by a single transistor stage.

Av       =       (R4 + R5)   /   R4


The resistors R1 and R2 are chosen to set the base of TR1 to around the mid point. If some current limiting is required then it is possible to place a resistor between the emitter of TR2 and the supply.
