Abstract
A digital-to-analog converter circuit including a plurality of digital-to-analog converter cells is provided. A first digital-to-analog converter cell of the plurality of digital-to-analog converter cells includes 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. A second digital-to-analog converter cell of the plurality of digital-to-analog converter cells includes 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. 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. The third voltage is constantly between the upper threshold voltage and the lower threshold voltage.
