A current-to-voltage converter for providing a voltage signal based on a current signal has a first active stage having an input and an output. The first active stage is configured to receive the current signal at its input and provide the voltage signal at its output. In addition, the current-to-voltage converter has a second active stage that is coupled between the output of the first active stage and the input of the first active stage. The second active stage is configured to provide the input of the first active stage with a feedback signal that frequency-selectively counteracts amplification, by the first active stage, of signal components of a current signal applied to the input of the first active stage that have a frequency outside of a prescribed useful frequency band. |
