Abstract
A track and hold signal processing system is capable of driving 256 gray scale active matrix LCD displays at speeds limited only by the electrical characteristics of the display. The quiescent power dissipated by the system is substantially less than known track and hold drivers due to separation of the tracking circuit from the hold circuit resulting in optimization of the tracking function.
