This paper describes the design of amorphous silicon (a-Si:H) logic circuits using static and dynamic programmable logic arrays (PLA's) as the baseline examples. The PLA's are designed with n-channel a-Si:H thin film transistors (TFT's) manufactured in a low temperature (180°C) 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.
