Druckmessanordnung

A pressure measuring arrangement has a pressure sensor structure comprising a pressure-dependent measuring capacitance, a pressure-independent reference capacitance and an evaluation circuit which derives the pressure from the capacitance measurement. To improve the linearity error, the pressure sensor structure includes a further pressure-dependent capacitance, whereby the evaluation circuit exhibits the following transfer function: Formula I, where C<-s is the measuring capacitance, C<-r the reference capacitance and C<-f the further capacitance.
