Low power operation is a driving requirement for the advancement of portable consumer electronics. As products get smaller and have more functionality the device integration requirements get tighter. This is certainly true of small format LCD applications like PDAs and cell phones. Recent advances in LCD technology have allowed for advanced circuitry to be built on the glass. This allows for the unique opportunity to integrate the LCD column driver with other circuitry rather than the traditional flip chip mounting on the glass. The integration of these D/A converters with digital circuitry presents a new set of design considerations. These considerations allow for the exploration of non-traditional architectures and algorithms. This work will explore these design considerations in detail and present a novel algorithm for conversion as well as a system implementation of this algorithm. The system implementation is compared to a standard linear converter to weigh the relative advantages of each. A high performance dynamically biased amplifier is developed for use in the D/A converter. This amplifier has a high slew rate while consuming a small amount of quiescent power.
