  • Digital-to-analog converters with reduced parasitics and associated methods
    Patent number: 6768440
    Abstract: A digital-to-analog converter (DAC) converts a digital signal into an analog signal. The DAC comprises a first capacitor network, a second capacitor network, a first amplifier, and a second amplifier. The first capacitor network includes at least one capacitor that has a weighted capacitance value. Similarly, the second capacitor network includes at least one capacitor that has a weighted capacitance value. The first amplifier has an input that couples to the first capacitor network. The first amplifier also has an output that couples to, and drives, the second capacitor network. The second amplifier has an input that couples to the second capacitor network. The output of the second amplifier constitutes the analog signal.
