Claim Text:
1. A digital-to-analog converter circuit comprising a plurality of digital-to-analog converter cells comprising: a first digital-to-analog converter cell comprising a cell control module configured to provide alternatingly a first voltage and a second voltage to a first electrode of a capacitive element of the first digital-to-analog converter cell based on a digital input signal during a predefined time interval, wherein the first voltage is higher than an upper threshold voltage corresponding to a first digital threshold level of the digital input signal and the second voltage is lower than a lower threshold voltage corresponding to a second digital threshold level of the digital input signal, and a second digital-to-analog converter cell comprising a cell control module configured to provide a third voltage to a first electrode of a capacitive element of the second digital-to-analog converter cell during the predefined time interval, wherein the third voltage is constantly between the upper threshold voltage and the lower threshold voltage during the predefined time interval.
