Abstract
Embodiments of the invention are directed to a current sensor that includes a current controlled oscillator circuit configured to receive an input current and to provide an output signal having an output frequency which is dependent on the input current. The current sensor further includes a feedforward circuit configured to adapt a reference voltage of the current controlled oscillator in dependence on an instantaneous current value of the input current.
