Simple Two Transistor Oscillator. This small experimental two transistor oscillator circuit can easily create audible frequencies within the range between 100 Hz and 2 kHz, operating a little loudspeaker. The circuit could be driven through 4nos of AA cells or constant 6 volt power supply. Similarly, an overdriven transistor amplifier can take on the characteristics of a controlled switch having essentially two levels of output. Today's electronics engineers have the ability to design circuits using premanufactured building blocks such as power supplies, resistors, capacitors. Power Supply. The circuit provides similar efficiency to Figure 2 with a supply voltage of approximately 36 volts approximately, although with a somewhat reduced gain and input impedance. For highest output, a slightly more than 500mV RMS may be required at the input, and the input impedance is around 15k. Another Simple 10 watt amplifier design. A transistor is a semiconductor device used to amplify or switch electrical signals and power.The transistor is one of the basic building blocks of modern electronics. It is composed of semiconductor material, usually with at least three terminals for connection to an electronic circuit.

The power amplifier circuit is meant to raise the power level of the input signal. To get large power at the output, the input-signal voltage must be large. That is why, in an electronic system, a voltage amplifier circuit always precedes a power amplifier circuit, as shown in the block diagram of the amplifier circuit (Figure 1).
