Abstract
The method and circuit arrangement both minimize stray electromagnetic interference in an electronic circuit, in which symmetric measurement signals are evaluated. Both inputs (InP, InM) of an evaluation circuit () are provided with a bank of switchable capacitors (C) individually or in groups, which are connectable with the respective inputs. A predetermined interference signal is applied to the respective inputs (InP, InM) and individual ones or groups of the switchable capacitors (C) are selectively connected with the inputs (InP, InM) so that a maximum suppression of the predetermined interference signal can take place. Data regarding the capacitance values selected during the suppression of the predetermined interference signal is stored in the memory () of a switching controller () during selective switching so that the same adjustment occurs automatically during subsequent operation cycles of the circuit arrangement.
