A 5 to 130 V level shifter composed of thin gate oxide dual terminal drain PMOSFETS

The market demand for high performance and cost effective flat panel display (FPD: e.g. plasma display, electroluminescent display) system has mandated that FPD driver designs need to be more cost effective. The driver plays a vital role in determining the FPD (system) performance and manufacturing cost as well as the panel itself. The driver is basically a device which can translate digital data signals (typically 5 V-logic) to the series of high voltage outputs (60 to 300 V) for the panel electrode load array. To reduce the manufacturing cost, this paper describes a study of the novel 5 to 130 V level shifter with Dual Terminal Drain PMOSFETs (DTDPMOS) for the first time. To adopt this level shifter, although the driver IC consists of both high and low voltage CMOS, the high voltage CMOS can be realized with the same thin gate oxide as the low voltage CMOS
