So here we are talking about that Phase Splitter circuit which is also one type of BJT means bipolar junction transistor configuration. Now in this type of setup what happens is, we give only one sinusoidal input signal from outside but then this one signal gets divided into two different outputs. That two outputs come […]

So here we are talking about this Common Base Amplifier. Right. That one is just another kind of BJT setup. We also call it Bipolar Junction Transistor. Now in this setup we got this base terminal of the transistor and that one is shared by both the input signal and the output signal. So we […]

So both Class B amplifier and Class AB amplifier types are having this special output stage which we call push-pull type right? And in this output section we always got two power transistors or maybe sometimes two FETs also that are joined or arranged in one special manner so that these two can take the […]

We already saw in our earlier tutorial on FET amplifiers that we can make simple one-stage amplifiers using JFETs or junction field effect transistors, right? But then we have other types of field effect transistors too and these can also be used to build an amplifier. So now, in this tutorial we will look at […]

In this post, we are talking about amplifiers and filters. These are two very common types of electronic circuits that we use a lot. Now if we see how they work then we can say that amplifiers do amplification and filters do filtration. That is why we call them that. Amplifiers and Filters Together But […]

The Input Impedance ZIN, or what people call as the Input Resistance, is important thing when making transistor amplifier circuits. It helps us to tell what kind of amplifier it is by looking at input and output impedance and also power and current ratings. Now amplifier impedance value is very important for circuit analysis, especially […]
