ABSTRACT:
A current integrator for generating an output voltage (Vo) in response to an input current (Ii) to be integrated. The input current is applied to an integration capacitor via a current-current converter. This enables one end of the integration capacitor to be connected to a fixed voltage and to be implemented by means of a MOS transistor which occupies a comparatively small area. A further area reduction is possible by making the current gain (K) of the current-current converter smaller than 1.
