Abstract :
This paper describes the design of amorphous silicon (a-Si:H) logic circuits using static and dynamic programmable logic arrays (PLApsilas) as the baseline examples. The PLApsilas are designed with n-channel a-Si:H thin film transistors (TFTpsilas) manufactured in a low temperature (180degC) process for flexible substrates. Measured and simulated results demonstrate that dynamic circuits are the best design approach, from both a power and delay viewpoint, for a-Si:H flexible logic circuits.
