So, in this project, we are going to design a simple audio amplifier circuit using a C NPN Power transistor. The transistor is available in the TO package. Due to its high current gain and collector current, it is very commonly used in High power audio circuits or AF amplifiers. This project is sponsored by PCBWay. The working of this audio amplifier circuit using C is as following. Audio input from a device such as a PC or a smartphone is taken as an input to the circuit.

Technical Details


This is a video amplifier splitter circuit or the video splitter circuit. It is designed to take video signal is stronger and compensate for the loss of signal. Also, it is a video splitter up to three outputs. So, it is suitable for display on several television screens, or videotapes recording at the same time, too.

Now, may no a videotape. The advantage of this circuit is inexpensive, easy, and more detail in the circuit below. The input impedance of the circuit is determined by the value of R1. The input signal enters through C2 to the base of Q1.

And, the VR1 adjusts the level of the signal swing. The output of Q1 is connected directly to the base of Q2. The amplified gain of the circuit is determined by adjusting VR2. Which it is in the feedback circuit, between collector pin of Q2 and emitter pin of Q1. The based on the used components in the circuit.

We can get the gain of 1. Thus, if the load is 75 ohms. The load will reduce the gain of the final amplifier section is half. The output signal is only times. You can change the resistance of R9 to suit the application. For example, if only single-channel networks. You use R9 is ohms. But if the second channel is used for the network. The resistor R9 should be 82 ohms, the current in the circuit will decrease.

The LM is the main of the Dc voltage Regulator circuit in this project. I think you still know it very well, popular IC. You can assemble all components on a perforated board. You should put carefully the device in the circuit. Points of caution are capacitors, diodes, and transistors. You put always the correct way. When you sure that the circuit is complete. Then, enter the power to the circuit to test by following method. You can adjust VR1 in two ways.

First, adjust VR1 until the voltage at the base of Q1 is equal to 1V. And, there is a voltage drop across R7. Then, adjust VR2 to the lowest rate of gain. Next, connect the TV or monitor to output. And, adjust VR1 until the test signal without distortion. This circuit requires enough power supply. Do you have this one? If you do not have it. Look: A lot of Power supply circuit.

I always try to make Electronics Learning Easy. Q2 is upside down. Feedback should come from the output emitter follower to reduce the output impedance and eliminate the interaction of the terminations.

In fact, the output emitter follower should really be a totem-pole type circuit. Lastly, the uF output caps are too small a value — there will be vertical-tilt in the output video at high APL.

Class D amplifiers, first proposed in , have become increasingly popular in recent years. What are Class D amplifiers? How do they compare with other kinds of amplifiers? Why is Class D of interest for audio? Find the answers to all these questions in the following pages. The goal of audio amplifiers is to reproduce input audio signals at sound-producing output elements, with desired volume and power levels—faithfully, efficiently, and at low distortion. Audio frequencies range from about 20 Hz to 20 kHz, so the amplifier must have good frequency response over this range less when driving a band-limited speaker, such as a woofer or a tweeter. A straightforward analog implementation of an audio amplifier uses transistors in linear mode to create an output voltage that is a scaled copy of the input voltage.

This is completely portable; you can use this small audio amplifier circuit with mobile phones, small mp3 players, laptops, and so on. Moreover you can save some money; the circuit connections will be reduced, the circuit size will be reduced. This circuit is extremely cheap and needs only a few electronic components. This is an electrolyte capacitor.

Documentation Help Center Documentation. Define the vector of base currents and minimum and maximum collector-emitter voltages by double clicking on the block labeled 'Define Conditions Ib and Vce '. Run the tests and generate plots of the curves by clicking in the model on hyperlink 'plot curves'. This type of plot can be compared against a manufacturer datasheet to confirm a correct implementation of the transistor parameters. You can also use this model to examine the transistor characteristics in the reverse region by specifying a range of negative Vce values. In this region, the gain is defined by the Reverse current transfer ratio BR parameter. Increase this parameter above one to produce a reverse current gain. The plot below shows collector current Ic versus collector-emitter voltage Vce characteristics for different levels of base current Ib.
