Abstract
An apparatus for correcting a mismatch between a first segment and a second segment of a Digital-to-Analog Converter, DAC, is provided. The first segment generates a first contribution to an analog output signal of the DAC based on a first number of bits of a digital input word for the DAC converter, and the second segment generates a second contribution based on a second number of bits. Further, the apparatus comprises a first processing circuit for the first number of bits comprising a first filter configured to modify the first number of bits to generate first modified bits, and a second processing circuit comprising a second filter to modify the second number of bits to generate second modified bits. The apparatus additionally comprises an output configured to output a modified digital input word for the DAC, which is based on the first modified bits and the second modified bits.
