Abstract:
An integrated circuit capable of controlling the level of an electrical signal between a high and a low level, the integrated circuit comprising:a signal path for carrying the signal between a driver circuit and a receiver circuit; and a plurality of level control sub-circuits connected to said signal path, each of said plurality of level control sub-circuits comprising: an n-channel field effect transistor having its gate connected to a low voltage source substantially equal to the low level, having its drain connected to a high voltage source substantially equal to the high level, having its source connected to said signal path; a p-channel field effect transistor having its gate connected to said high voltage source, having its drain connected to said low voltage source, and having its source connected to said signal path; and, wherein said n-channel transistor will be biased on when said signal path is less than the low level and said signal path will be charged by said high voltage source, and wherein said p-channel transistor will be biased on when said signal path is greater than the high level and wherein said signal path will discharge to said low level voltage.
