Transistor Sizing of LCD Driver Circuit for Technology Migration

Design automation of LCD driver circuits is not sophisticatedly established. Display fineness of an LCD panel depends on a performance metric, ratio of pixel voltage to video voltage (RPV). However, there are several other important metrics, such as power consumption and area, and the best circuit cannot be decided uniquely. This paper proposes a design automation technique to provide several circuit design results with different performance to designers so that designers can select an appropriate design among them. The proposed technique is experimentally evaluated with an actual design data, and it is found that the proposed method reduces circuit area in addition to improving RPV. Also the proposed technique is experimentally verified from points of solution quality and computational time.
