A thin film transistor (TFT) is an insulated-gate field effect transistor that is fabricated using thin film techniques on an insulating substrate rather than a semiconductor. Integrated circuits (IC) built using polysilicon thin film transistors at low temperatures have attracted much attention in .....

Almost all circuit systems require a voltage reference. A voltage reference provides a temperature and supply independent voltage. In addition, this voltage reference mudt be able to operate under low-voltage low-power conditions and can be implemented in standard CMOS process instead of expensive B.....
