A continuous-time delta sigma modulator, having an integrator and a comparator clocked with a clock frequency that are connected in a feedback loop, having a voltage source that is connected to the comparator for applying a threshold voltage to the comparator, in which an integration time constant of the integrator has a first resistor and a first capacitor, in which the voltage source has a second resistor and a second capacitor for setting the threshold voltage, in which the first resistor and the second resistor are part of a resistor pairing structure, and in which the first capacitor and the second capacitor are part of a capacitor pairing structure.
