Hello fellows, I hope you all are doing great. In today’s tutorial, we will have a look at Analyze High Frequency Response of Amplifier.In the previous tutorial low frequency response of amplifier we have discussed that coupling and bypass capacitors has an effect on the voltage gain of amplifier at les frequency at a point…

### Analyze Low-Frequency Response of Amplifier

Hello fellows, I hope you all are doing great. In today’s tutorial, we will have a look at Analyze Low-Frequency Response of Amplifier. For capacitively coupled amplifier if signal frequency is less than critical value then there will be an effect on voltage gain and phase shift. At less value of frequency, the reactance of…

### How Decibel (dB) Express Amplifier Gain

Hello fellows, I hope you all are doing great. In today’s tutorial, we will have a look at How Decibel (dB) Express Amplifier Gain. A decibel is a unit of a logarithmic corresponding to one 10th of bel. It used to define the ratio between one value of power to other on a logarithmic scale.…

### How Circuit Capacitances Affect Frequency Response of Amplifier

Hello fellows, I hope you all are doing great. In today’s tutorial, we will have a look at How Circuit Capacitances Affect Frequency Response of Amplifier. In amplifier circuits coupling and bypass, capacitors look short to ac at midband frequencies (MidBand frequency or sub-6 is spectrum used for wireless data transmission. It works among the…

### How to Troubleshoot FET Amplifiers

Hello fellows, I hope you all are doing great. In today’s tutorial, we will have a look at How to Troubleshoot FET Amplifiers. The FET is a type of transistor-like the BJT that uses an electrical field to regulate the movement of current. It has three terminals like the BJT first is gate, drain and…
