Abstract
A control unit for a transportation device has a processing unit that is supplied with power by a first supply voltage and has a signal converter for converting input analog signals to digital signals. The signal converter has an analog converter stage for generating a modified signal from the analog signal and a digital converter stage for generating a digital signal from the modified signal. The analog converter stage has a signal integration stage connected to a signal amplitude comparator; and the digital converter stage has a scanning stage to whose output the analog-to-digital-converted digital signal is applied. The digital converter stage comprises configurable logic circuits provided on the chip of the processing unit; while the analog converter stage comprises components outside the processing unit. The analog converter stage is supplied with voltage by a second supply voltage different from the first supply voltage.
