So in our previous tutorial we already saw how a Thyristor or we can say Silicon Controlled Rectifier (SCR), is made and how that basic working happens. We saw how this device looks like and how it starts and stops conducting. That was only the construction and simple working part. But now in this part, […]

Understanding BJT Common Collector Amplifier Circuit with Formulas
So here we are talking about one more type of BJT amplifier, that is called Common Collector Amplifier. In this type of connection we give the input signal to the base pin of the transistor and then we take the output signal from the emitter pin. That means here the collector pin is working like […]
Understanding MOSFET Amplifier Circuit
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 […]
Understanding Frequency Response of an Amplifier Circuit
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 […]
Understanding Input Impedance of a BJT Amplifier Circuit
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 […]
Understanding Distortion in Amplifier Circuits
In order for a signal amplifier to do its job properly and make sure that the output signal does not get distorted in any way it is really important to have some kind of DC Bias applied to its Base or Gate terminal. You see, a DC bias is necessary because it allows the amplifier […]
