In the context of a top-down refinement process for mixed-signal system designs, analog parts are either described at the most abstraction levels or alternatively at the lowest: there is a lack of descriptions at the intermediate levels. The paper deals with the modeling at these levels. It presents as a running example an operational amplifier model that has been built at an intermediate abstraction level in order to fill the gap. As far as we know, there is no equivalent in the literature. The results obtained with a SystemC-AMS simulation of this model are shown.
