ABSTRACT:
A voltage/current converter circuit includes a bridge configuration having a first current path with a first resistor, a first transistor, and an input node to receive a ramp voltage to be converted, and a second current path with a second resistor and a second transistor. A current passes through the second current path. An amplifier arrangement balances the bridge configuration by providing an output signal to a control terminal of the first transistor and/or to a control terminal of the second transistor.
