Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

This is a (inverting) high pass filter. Resistance R1 can be chosen, resistance R2 is defined by the desired amplification k, capacitance C is defined by the desired cut-off frequency.

The example is taken from: U. Tietze and C. Schenk, Halbleiter-Schaltungstechnik (German), 11th edition, Springer 1999, Chapter 13.3
