Q. Input offset current of operational amplifier?

The adverse effect of the input bias current mentioned would be nulli?ed if both inputs were connected to equal resistances (one of which could be a passive resistor) and if IBp = IBn. The differential input would then be zero. However, if the input bias currents are unequal, as shown in Figure, there will be a ?nite differential input voltage. It then becomes necessary to specify the difference between the bias currents, and this is the input offset current IOS,

A typical value for IOS is 20 nA. Both IB and IOS are usually measured with the output at 0 V; but in practice the output voltage has little effect.
