Abstract
A circuit for use in conjunction with a portion of a core of an integrated circuit, for shifting a signal from a first voltage level to a second voltage level, wherein the circuit is formed using the same process type transistors (i.e., low voltage transistors) as are used in the core of the integrated circuit.
Claims18
An integrated circuit, comprising:
- a core portion including a plurality of transistors made using a first process technology;
- and
- a level shifting circuit, wherein said level shifting portion includes transistors made only using the first process technology;
- wherein the level shifting circuit further comprises a pulse generating circuit for momentarily activating a portion of the transistors of the level shifting circuit, thereby reducing the amount of power consumed by the level shifting circuit.
