HIGH-SPEED VOLTAGE-LEVEL CONVERTER USING CAPACITOR

摘要

A voltage-level convertor including a switch and a capacitor which receives an input signal of a first voltage range and generates a level-converted signal of a second voltage range. The switch operates in a low voltage level, and hence, the switch can be implemented as a thin oxide device that responds quickly to the input signal. The capacitor is coupled between the switch and an output node. The capacitor is charged to a predetermined voltage. In response to receiving the output from the switch, an output signal with a converted voltage level is generated from the conductor of the capacitor connected to the output node.
