Abstract
A level shifting circuit with a thin gate transistor connected to the input of the output stage is presented. The level shifting circuit has an input stage that receives an input that is at first voltage. A transistor with a thin gate oxide has one terminal connected to the input stage and another terminal coupled to an input of the output stage. The output stage of the level shifting circuit is implemented with thick gate oxide transistors.
