Abstract
A voltage-current converter includes a first input stage and a second input stage with a first transistor and a second transistor driven by the first input stage and by the second input stage, respectively. First and second current generators are coupled to current lines of the first transistor and of the second transistor. At least one resistor couples the current lines of the first transistor and of the second transistor, where the ends of the aforesaid resistor are coupled to feedback terminals of the input stages so that an input voltage applied between voltage input terminals of the input stages is converted into a current on respective current output terminals of the converter. The converter includes switching circuits for coupling the first and second current generators alternately to the current line of the first transistor and to the current line of the second transistor.
