Patent ID: 7282815

Claim:
A method for minimizing stray electromagnetic interference in an electronic circuit, in which symmetric measurement signals of a measuring bridge are evaluated, said method comprising the steps of: conducting a bridge diagonal voltage symmetrically to both inputs (InP 1 InM) of an evaluating circuit ( 2 ); providing a controllable switching arrangement in the evaluating circuit ( 2 ) for switching in switchable capacitances (C z ) providing both inputs (InP, InM) of an evaluation circuit ( 2 ) with switchable capacitances (C z ); applying a predetermined interference signal to said inputs (InP, InM); and switching in said switchable capacitances (C z ) by the controllable switching arrangement; selecting a combination of the switchable capacitances (C z ) in such a way that a maximum suppression of said predetermined interference signal takes place at an output of the evaluating circuit ( 2 ); and storing a selected adjustment corresponding to the selected combination of said switchable capacitance (C z ) in the evaluating circuit ( 2 ).
