Abstract :
A new source follower type analog buffer used as an output buffer for the data / column driver of an Active Matrix display is presented in this paper. The proposed buffer is implemented with low temperature polycrystalline silicon thin film transistor (LT poly-Si TFTs) and the main advantage of the buffer is its high immunity to the threshold voltage variation of the LT poly-Si TFTs. The functionality of the buffer is verified through simulation with HSpice, using for the simulations parameters extracted from fabricated LT poly-Si TFTs in order to obtain realistic simulation results.
