Abstract :
Due to poor mobility, coarse design rule, and poor parameter uniformity, improvement in design methodology becomes critical in the TFT-based system-on-panel design. We present a new TFT based inverting level shifter which has been optimized for LTPS TFT properties for superior characteristics. Compared to a power hungry, high speed offset voltage type level shifter, the proposed circuit reached the same speed with only 10% power and 51% real estate. We have fabricated and tested the circuit with 4 micron LTPS TFT technology
