Take two bc547 transistors and connect the emitter pin of the first transistor with the base pin of the second transistor. Connect a 10K-ohm resistor between the base and collector pin of the first transistor. Join the negative wire of the speaker with the collector pin of the first transistor as shown above.

Bode. Run the frequency-domain analysis to see a plot of the gain of the amplifier. As-is, it's about +38dB in the passband. That's a voltage gain of 10^ (38/20) = 79. Notice that our hand calculations indicated a gain of about 88, so that's pretty close! Now remove CE, and re-run the Bode analysis.

In today’s tutorial, we will have a look at BJT as an Amplifier. A transistor is an electronic component that has three terminals. Terminals are base-emitter, collector and base. It used in different electronic projects and circuits for switching and amplification process. Amplification is process through which weak input signal is amplified ...

A full-fledged stereo power amplifier with the TDA1517 chip. It is powered by single voltage, achieves 2×6W output power at 4 Ω load. The whole is designed as a small module with dimensions of 30mm × 38mm, which “will fit anywhere”. The TDA1517 amplifier module can be used in self-made sound equipment or mounted in.

sistor (BJT) circuits are used as small-signal amplifiers. The term small-signal refers to the use of signals that take up a relatively small percentage of an amplifier’s operational range. Additionally, you will learn how to reduce an ampli-fier to an equivalent dc and ac circuit for easier analysis, and you will learn about multistage amplifiers.

1 2N3904 BJT Transistor 1 2N7000 MOSFET Transistor 3. Introduction Multistage amplifiers made up of single transistor amplifiers connected in cascade. The first stage usually provides a high input impedance to minimize loading the source (transducer). The middle stages usually account for most of the desired voltage gain.

https://www2.seas.gwu.edu/~ece20/spring01/benfinalreport.pdf
Abstract of Design Project Stereo Amplifier By Ben Ruppel This report covers the design and implementation of a multi-stage stereo audio amplifier with its own voltage regulator, LED display, and digital volume control for each channel. The input can come directly from a CD audio player or similar device, and typical 8 Ohm speakers are driven.
