Abstract

A current-voltage converter with a current reflector, for which the input current includes a fixed component and a variable component, includes 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 a resistor for converting the current into a voltage, arranged between the output and ground. The gate of each MOSFET transistor is connected to one of the reference voltages. The input for the current to be converted is connected to the output through one of the MOSFET transistors. The converted further 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.
