Abstract

The invention relates to a voltage to current converter suited for integration. The voltage to current converter combines the outputs of two voltage to current converting circuits whose operating input levels are different from each other so as to prevent the generation of direct current offset voltage. The voltage to current converter is suitable for the construction of a filtering circuit.
