Abstract: A reference circuit arrangement comprises a branched current path connecting a first and second terminal via an intermediate terminal. The intermediate terminal is connected to a reference terminal. A current path is coupled between the first and second terminal via the reference terminal. A feedback loop is connected to the first and second terminal and designed to control, at the first and second terminal, a virtual ground potential. A reference path is connected to the feedback loop having a reference input for receiving from the feedback loop a reference current and reference output to provide a reference voltage.
