Abstract
In one embodiment an analog-to-digital converter circuit has an input for receiving a first analog signal level and a second analog signal level, a ramp generator adapted to provide a ramp signal, a comparison unit coupled to the input and the ramp generator, a control unit coupled to the comparison unit the control unit having a counter, the control unit being prepared to enable the counter as a function of a comparison of the ramp signal with the first analog signal level and the second analog signal level, and an output for providing an output digital value as a function of a relationship between the first analog signal level and the second analog signal level. Therein the ramp signal has at least one linearly rising and at least one linearly falling portion and an adjustable shift at a reversal point between the rising and the falling portion of the ramp signal, the shift depending on the number of rising and falling portions of the ramp signal.
