Abstract
A level shifting circuit is provided. Thin oxide devices are utilized to reduce the threshold, and thick oxide devices are utilized to protect the thin oxides from breakdown. An input voltage input voltage swings between a low supply voltage and ground. An output voltage swings between a high supply voltage and the ground. An inverter with input connected to the input voltage, outputs an inverted input voltage. The input voltage is subsequently between 0.5V to 2.5V, and the output voltage is subsequently between 3V to 10V.
