1 Answer

Answer :

Definition of parameters of OPAMP is follows: 

i) Input Offset Voltage: Input offset voltage is defined as the voltage that must be applied between the two input terminals of an OPAMP to null or zero the output 

ii) Input offset Current: The input offset current Iio is the difference between the currents into inverting and non-inverting terminals of a balanced amplifier. 

iv) Input Bias Current: The input bias current IB is the average of the current entering the input terminals of a balanced amplifier. 

iv) Output offset voltage: Output offset voltage is the output of an operational amplifier when the two inputs are shorted together (and often tied to ground) and output voltage is obtained non zero such voltage is output offset voltage of opamp.
