Abstract
In various embodiments an analog-to-digital converter arrangement is provided, which may include an input terminal configured to receive a signal to be converted; a reference terminal configured to receive a reference signal; a voltage domain specific reference terminal configured to receive a voltage domain specific reference signal; an analog-to-digital converter circuit coupled to the input terminal, the reference terminal, and to the voltage domain specific reference terminal configured to compare the signal to be converted with the voltage domain specific reference signal, thereby generating a first digital comparison signal, and to compare the reference signal with the voltage domain specific reference signal, thereby generating a second digital comparison signal; and a ratiometric circuit configured to determine a digitally converted signal of the signal to be converted using the first digital comparison signal and the second digital comparison signal.
