description: This work is devoted to digital-to-analog converters with variable bias voltage. In typical segmented DAC, there is a risk of non-monotonicity when switching between segments, bit if we ensure the weights of the weighing elements of different segments, then this risk can be eliminated. The aim of the work is to develop and simulate a DAC with an alternating bias voltage and compare its characteristics with the characteristics of a typical segment DAC, in which weights are set only by scaling geometric dimensions. In a variable bias DAC, this relationship exists between segments. Also, in the process of developing digital-to-analog converters, thermometer and address decoders were implemented. In this work, several types of current mirror circuits were discussed, and the optimal current mirror circuit was chosen. The analysis of the results obtained allows us to conclude that the differential and integral non-linearities of the developed DAC with an alternating bias voltage are inferior to the nonlinearities of a typical segmented DAC, but at the same time the DAC with an alternating bias voltage has a guaranteed monotonicity of the conversion characteris
