DE 102008033180 A1 UPAB: 20100204 NOVELTY - The method involves adjusting a potential value an input of a comparator by capacitors of a capacitor network, where the value is smaller or larger than another potential value. The capacitors are charged and/or discharged still potential exceeds and/or falls below a predetermined threshold value, where the potential lies at the comparator. A signal for testing an analog-to-digital converter, which is provided with the comparator and capacitor network, is produced, where the signal contains information about a frequency of adjusting one of the potential values. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an analog-to-digital converter with a comparator and a capacitor. USE - Method for generating a signal for testing an analog-digital converter (claimed) that is utilized for converting an analog input value to a digital output value and/or codes. ADVANTAGE - The method efficiently tests the analog-digital converter, without a need for external capacitor for testing the converter, and reduces storage requirement for self testing of the converter
