초록

An ultra low-power down-conversion level shifter using low temperature poly-crystalline silicon thin film transistors is proposed for mobile applications. The simulation result shows that the power consumption of the proposed circuits is only 17% and the propagation delay is 48% of those of the conventional cross-coupled level shifter without additional area. And the measured power consumption is only 21% of that of the crosscoupled level shifter.
