Patent abstract
A digital-to-analog converter and method for transforming a digital value into an analog signal are disclosed. The digital-to-analog converter has a voltage generator, a voltage selector, a multiplexer and a switch array. The voltage generator provides a first and second group of voltages. The voltage selector selectively outputs the first or second group of voltages according to a polarity signal. The multiplexer selectively outputs the digital value or a complementary value of the digital value according to the polarity signal. The switch array outputs one of the voltages received from the voltage selector according to the value output from the multiplexer.
