Abstract :
This talk discusses some recent progress in robust circuit/system design and test of flexible electronics. We will first give an overview of reliability simulation for predicting TFT degradation under bias-stress. A reliability analysis framework, which has successfully analyzed the reliability of an amorphous-silicon (a-Si) TFT scan driver for TFT-LCD displays, will be discussed [1]. We then discuss solutions that can make TFT circuits operable under a lower supply voltage and can equip them with post-fabrication tunability for reliability and performance enhancement. Specifically, we will present a new design style, named Pseudo-CMOS [2], which has been successfully validated in a p-type organic TFT technology [3] as well as in a n-type InGaZnO (IGZO) TFT technology.
