ABSTRACT:
A voltage-to-current converter is provided based on a pair of current sources providing current to two other pairs of current sources, one pair in the input stage and one pair in the output stage. Careful matching of current source pairs provides a large common mode rejection ratio and a large power supply variation rejection ratio.
