Abstract
A circuit for converting an input signal at a first voltage level to an output signal at a second voltage level uses only thin oxide transistors. The circuit includes a first unit operating at a first power supply voltage and receiving the input signal, a second unit operating at a second power supply voltage, and a third unit coupling the first unit to the second unit. The third unit enables generation of the output signal. Use of an extra fabrication mask for thick oxide transistors is avoided by using only thin oxide transistors.
