Abstract
A sigma-delta analog-to-digital converter array including two cascaded sigma-delta modulators, the two sigma-delta modulators being multi-bit sigma-delta modulators. The sigma-delta analog-to-digital converter array is preferably a third order device and supplies a digital output signal corresponding to a sigma-delta converter with 7-bit quantization. To this end, a second order sigma-delta modulator with 3-bit quantization and a first order sigma-delta modulator with 5-bit quantization may be used.
