Abstract: A differential delta-sigma-modulator has an integrator including a pair of single-ended amplifiers. A sample clock is driving a first switchable capacitor configuration and a second switchable capacitor configuration at a predetermined switching cycle. The first switchable capacitor configuration is adapted for sampling respective outputs from the pair of single-ended amplifiers on a pair of output sampling capacitors in the first part of the switching cycle. The second switchable capacitor configuration is adapted for charging a common mode capacitor with the average voltage of the voltage sampled by the pair of output sampling capacitors in the second part of the switching cycle. The voltage across the common mode capacitor represents the common mode voltage for the integrator.
