ABSTRACT:
The invention relates to an integrated voltage-current converter circuit for generating a current which produces a voltage drop across a reference resistor, which voltage drop is determined by an input voltage. In order to compensate for the spread in width of the reference resistor formed in the integrated circuit, this reference resistor is formed by two parallel-connected resistors having the same resistance per unit area, the same length and different widths, and the compensated output current is formed by the difference between the currents which flows through these resistors.
