    Abstract: A method and a digital-to-analog converter (DAC) circuit involve forming an analog signal using charge sharing operations. The DAC circuit includes a plurality of digital components with associated parasitic capacitances. The digital components are activated based on a digital input code, such that charge is shared among the parasitic capacitances to form a first analog signal proportional to the digital input code. The digital components can also be activated based on a complementary code to form a second analog signal. The first analog signal and the second analog signal can be used to form, as a final output of the DAC circuit, an analog signal that is linearly proportional to the digital input code.
