For most systems single nbsp transistor amplifier does not provide sufficient gain or output impedance matching The solution is only to combine multiple stages of amplification In this amplifier circuit we are going to show a simple two-transistor amplifier In the single-transistor amplifier circuit we have made a very simple amplifier with one transistor one resistor and one capacitor but the amplifier has been designed with two transistors We have designed this amplifier by using two transistors including PNP and NPN transistors and we adopted the overall topology of the Sziklai pair The two-transistor amplifier provides a reasonably high impedance
