Abstract

This paper proposes the gate driver circuit which is able to compensate VTH shift for pull-down unit. Using 4T1C circuit configuration, we can improve the reliability of pull-down unit for continuous bias stress. In addition, a simplified circuit is obtained since Q and VOUT node share the same circuit configuration.
