Power Amplifier Transistor Amplifier. I simulated a basic amp with ltspice then added a push pull pair to the original i attach both files. Today we are going to make 600 watts amplifier.
A transistor that is manufactured to suit the purpose of power amplification is called as a power transistor. Which the q1 is a first preamplifier to increase a little signal up. An amplifier is an electronic circuit that uses a small input signal to control a larger output signal.
Since the 1970s most modern audio amplifiers are based on solid state transistors especially the bipolar junction transistor bjt and the metal oxide semiconductor field effect transistor mosfet.
A power transistor differs from the other transistors in the following factors. In class ab operation each output device conducts more than half of the input signal cycle. It is a transistor amplifier. The below figure shows how a transistor looks like when connected as an amplifier.
