high voltage gain :- common base since the ratio of output impedance to the input impermanence is very high in common base mode

high current gain :-common collector since it is the ratio of Ie/Ib

What is kirk effect?

The Kirk effect occurs at high current densities in bipolar junction transistors and causes a dramatic increase in the transit time of a transistor.


What are electrodes called in a MOSFET transistor?

The terminals on a MOSFET are called the "Source", "Drain", and "Gate". Just as with a bipolar junction transistor (BJT) the direction of current flow will be based on the doping configuration of the semiconductor. In a MOSFET, the doping configuration can be either n-channel or p-channel, but with MOSFETS, they also come in a "normally on" or "normally off" configuration, which is specified by being either "depletion mode" or "enhancement mode", respectively.


Why bjt is bipolar?

BJT stands for bipolar junction transistor because it is composed of two types of semiconductors (P and N-type) rather than just one type like a unipolar transistor. This allows for both electron and hole current flow in the device, giving it its bipolar characteristic.


What is FET?

FET is abbreviation of Field Effect Transistor. This is a transistor in which current is controlled by voltage only and no current is drawn. It is a high input impedence device and is used in computers, telecommunication and control circuits. This transistor is better in certain parameters as compared to BJT, that is Bipolar Junction Transistor.


What bias conditions must be present for the normal operation of a transistor ampilifier?

Assuming you mean a bipolar junction transistor (BJT): 1. Reverse bias on the collector-base junction. 2. Forward bias on the base-emitter junction, that is 3. Sufficient to give the correct operating point of collector voltage/collector current.
