What is the use of offset null in an opamp?
A: Any offset whether is voltage or current is an output error to contend with.
What are the two basic configurations in operational amplifier?
opamp is a device used to amplify ac as well as DC input signals. It is called as operational amp becoz it is used to perform all mathematical operations. Symbol of opamp indicates the direction of current.
Forward bias and reverse bias?
forward bias is in the direction a junction or vacuum tube wants to conduct currentreverse bias is in the direction a junction or vacuum tube opposes conducting current
What are the types of FET biasing circuit?
Various FET biasing circuits are as follows: 1. Fixed bias 2. Self bias 3. Potential divider bias 4. Current-Source bias
What is the reason for reverse saturation current?
its simple.reverse saturation current is because of the flow of minority carriers across the junction when the bias is changed suddenly from forward to reverse.this is why it doesnt depend on forward bias
What is the difference between constant current bias and current mirror circuit?
current mirror circuit produce more stability as compared to biased circuit.
What are characteristics of an ideal diode?
An ideal diode:Passes current in one direction only. (Under forward bias).Has no leakage current (passes no current under reverse bias).Has no forward voltage drop. (No voltage loss under forward bias - a real diode has Vd~=0.7)See links for more details.
What is the difference between the input bias current and the input offset current?
A: difference in bias current causes the other
What is the use of offset null in an opamp?
A: Any offset whether is voltage or current is an output error to contend with.
Does diode flow current in reverse bias?
Diodes will have a small leakage current in reverse bias. In most cases, this current can be considered insignificant and ignored.
What is a mirror with preconception?
there is no such thing but if you come across one it is a mirror that shows what you want it to show in other words, is bias.

opamp is a device used to amplify ac as well as DC input signals. It is called as operational amp becoz it is used to perform all mathematical operations. Symbol of opamp indicates the direction of current.
Why self bias is not suitable for enhancment type mosfet?
With the E-MOSFET, VGS has to be, 'greater than VGS(th) to get any drain current at all. Therefore, when E-MOSFETs are biased, self-bias, current-source bias, and zero bias cannot be used because these forms of bias depend on the depletion mode of operation. This leaves gate bias, voltage-divider bias, and source bias as the means for biasing E-MOSFETs.
What is forward bias current in semiconductor?
I think its related to junction of two dissimilar semiconductor (or semiconductor and metal) and not only a semiconductor. well when two opposite nature semiconductor (hetero or homo) are joined to form a junctions they allow the flow of current in one direction while blocks it in other direction. The applied bias V which will cause the current flow is called forward bias and the current flowing through the junction forward bias current.
Forward bias and reverse bias?
forward bias is in the direction a junction or vacuum tube wants to conduct currentreverse bias is in the direction a junction or vacuum tube opposes conducting current
How you differentiate base bias and emitter bias?
On the emitter there is base current which is basically a function of Beta and only at that particular current. Unfortunately the beta factor is a non linear function and it is strictly related to collector current
What are the types of FET biasing circuit?
Various FET biasing circuits are as follows: 1. Fixed bias 2. Self bias 3. Potential divider bias 4. Current-Source bias
