Abstract:
1. A current-voltage converter with a current reflector, the input current including a fixed component and a variable component, the converter including: an input for the current to be converted; an output for the converted voltage; two constant current sources each connected between the output and a respective reference voltage; at least one MOSFET transistor, mounted in series with each constant current source, and the gate of which is connected to one of the reference voltages; and a resistor for converting the current into a voltage, arranged between the output and ground, the input for the current to be converted being connected to the output through one of the MOSFET transistors; characterized in that it includes, for each MOSFET transistor, means for re-injecting into at least one of the current sources, a current equal to the current absorbed in the gates of the MOSFET transistors.
