Abstract
This disclosure provides systems, methods and apparatus for providing an output voltage to be used in a display device. In one aspect, a circuit may include switches and a digital-to-analog converter (DAC). A charge recycling circuit may include a capacitive voltage divider providing voltage supplies for the switches to select from and provide to the DAC. A storage capacitor may be configured to be coupled one at a time and in parallel with individual capacitors of the capacitive voltage divider. The storage capacitor may store charge that may be reused. Additionally, a data control circuit may provide control signals for the switches and the DAC.
