System and method for compact cyclic digital to analog converter

摘要

A system for implementing a cyclic digital to analog converter (c-DAC) is capable of supporting a large size liquid crystal display. The system includes an upper DAC stage configured to output a first voltage between a lower voltage supply (HVDD) and an upper voltage supply (AVDD). The system also includes a lower DAC stage configured to output a second voltage between the lower voltage supply (HVDD) and a ground. The upper DAC stage includes a single PMOS switch and the lower DAC stage includes a single NMOS switch.
