ABSTRACT:
An integratable circuit configuration includes an analog signal network being subject to fluctuations in a given way. An analog/digital converter is connected downstream of the analog signal network. A digital signal network is connected downstream of the analog/digital converter for receiving settable coefficients. An analog comparison network being subject to the fluctuations in the same given way receives an excitation signal and supplies a response signal in response to the excitation signal. An evaluation circuit is connected to the analog comparison network and to the digital signal network for comparing the response signal with a reference signal and setting the coefficients of the digital signal network as a function of the comparison. According to another embodiment, a digital/analog converter is connected upstream of the analog signal network. Then the digital signal network is connected upstream of the digital/analog converter.
