ABSTRACT:
An embodiment of a low-to-high-level voltage translator is proposed. This translator translates the low voltage swing signals for the core into high voltage swing signals of the I/O blocks. This translator may be particularly useful for high-speed application where the difference between the core and the I/O supply voltage is very large, e.g., the core is working at 0.8V and the I/O is working at 3.6V or higher without little or no static power dissipation. The proposed translator may give improved transition times and propagation delays as compared to conventional translators. The proposed translator may also use less hardware in comparison to other such translators.
