Abstract
A semi-conductor circuit arrangement for a continuous time sigma delta modulator for adding analog input signals to a digital fed back signal and for quantizing the totalled signal comprises a voltage to current conversion circuit (), an adding circuit () with a resistor ladder, a quantizing circuit () with comparator elements () and a digital to analog conversion circuit (). For each comparator element () its respective input signal is formed by a voltage which is released between a tap in front of a corresponding tapping resistor () in a first string of the resistor ladder and a tap in front of a corresponding tapping resistor () in a second string of the resistor ladder.
