bias current compensation circuit


Posted on Feb 7, 2014

This is design circuit of bias current compensation circuit. This circuit can operate from MW source resistances with little increase in the equivalent offset voltage. This circuit is based on LM11. This is the figure of the circuit. This is impressive considering the low initial offset voltage. The situation is much improved if the design can be

configured so that the op amp sees equal resistance on the two inputs. However, this cannot be done with all circuits. Examples are integrators, sample and holds, logarithmic converters and signal-conditioning amplifiers. And even though the LM11 bias current is low, there will be those applications where it needs to be lower.
