Abstract
A Novel level-shifter circuit for Display Panel Driver is presented. A Proposed level-shifter is for the high speed and high-voltage driving capability. In order to achieve this purpose, the proposed level-shifter restricts and separates the Vgs of the output driver's pull-up PMOS and pull-down NMOS with Zener diode. And a speed-up PMOS transistor is introduced to reduce delay. The control signal of speed-up PMOS was designed by bootstrapping method to minimize the gate to source (Vgs) voltage to avoid Vgs breakdown.
