There are 4 different amplifier classes.
Class A is used in applications where the output is an amplified  replica of the input signal. Class A consists of both small-signal and  large signal amplifiers if operated in the linear region at all times.  Class A also consists of Power Amplifiers which are a large signal type  amplifier that’s objective is to distribute power to a load. These  amplifiers are rated for more than 1W and needs a form of heat  dissipation when used in an application. Class A
Amplifiers achieve maximum signal when q-point is center of the ac load line.  
Class B is biased at cutoff, operating in the linear region for 180o of the input cycle and is in cutoff for 180o  . This class of amplifiers are more efficient than class A in terms of  output power to input power ratio. The class B amplifier however only  conducts for the positive have of a sinusoidal waveform. An operation  referred to as a push-pull consists of two Class B amplifiers working  together to achieve conduction on the negative portion of the cycle. 
Class AB is similar to Class B in the sense that it is more efficient  than a class A amplifier. A class AB amplifier in the push-pull stage  can be used to overcome crossover distortion which occurs when the dc  base voltage in a class B amplifier reaches zero. When this happens  neither transistor is conducting so the biasing is adjusted to overcome  the VBE of the transistors. 
 Class C is a nonlinear amplifier, meaning that the output is not a  replica of the output. The transistor is biased below cutoff with a  negative VBB supply putting the Q-point outside the load  line. The transistor is turned on for a short interval when the base  voltage exceeds the barrier potential of the base-emitter junction while  the AC source peak voltage is slightly greater than
Explain what is meant by ‘TFT’ that you always find in the specs for laptop displays.
TFT stands for Thin Film Transistor and is used to enhance the operation of the LCD displays.”The  thin film transistor (TFT) is a type of semiconductor device used in  display technology to enhance efficiency, compactness, and cost of the  product. In conjunction with its semiconductor properties, the TFT LCD  is an active matrix display, controlling pixels individually and  actively rather than passively, furthering the benefits of this  semiconductor device.”(Orient Display, 2022).
Discuss an application of Darlington Pair transistors.
A Darlington Pair transistor consists of two bipolar junction  transistors combined to yield a high current gain. The first transistor  amplifies then the second further amplifies. can consist of either two  PNP transistors or two NPN transistors connected back-to-back sharing a  common collector.

Frequently asked questions

How soon can I get my paper done?

It depends with your deadline. If you need your paper completed in 3 hours, we will deliver it in that time. All you need to do is indicate your deadline in our custom order page here. Alternatively, if you are sending us your instructions via email, please be sure to indicate your deadline.

Will it be completely original? I don't want to be caught in a case of Academic Integrity Violation.

We are as paranoid as you are. Maybe even more! And we understand that the greatest sin you can commit in your academic journey is plagiarizing your academic work. To that end, we have made sure that we check and double-check our papers using high quality plagiarism detection tools such as SafeAssign and Turnitin before submitting the paper to you.

Who is my writer? Is he/she a native English Speaker?

All our writers are native English Speakers. That is not to say that ESL writers are not good, we just prefer hiring native writers because we want the very best people working on your paper. This might mean paying a little bit more for your paper as opposed to when you pay a foreign company whose writers are non-native English Speakers.

What if I need revisions? Will your charge additional for this?

Of course not! If you do happen to require a revision on your paper, our team will handle it for you free of charge. Matter of fact, we won’t rest till you are happy with your paper. So, ask for as many revisions as you need, it’s completely FREE!

Will you give me my money back if I don't like my paper?

We have very few instances where we delivered a paper that a client didn’t fall in love with. But if it so happens that you don’t like your paper for any reason whatsoever, we’ll refund your money back no questions asked.

I have more assignments after this, can you help me with those too?

Of course! And what’s even better is that we can reserve a writer permanently to work on your entire class. This comes in handy for projects which build up on each other and where you need just one writer, one writing style.

I got my order information wrong, can I change that?

Yes you can. Just reach out to our support team via email ( or live chat here and they’ll help you change the instructions.

Can I place an order via email instead of going through the order page?

Yes you can. Email Anna at, she’s in charge of our sales team. Alternatively, you can talk to our Live Chat team here and request to speak to Anna.
