Patent ID: 7477086

Claim:
A method of level-shifting a signal comprising: converting a first single-ended signal to a first differential signal having a first voltage range by: receiving the first single-ended signal with a first non-inverting signal path; receiving the first single-ended signal with a first inverting signal path; coupling a first plurality of nodes in the first inverting path to a second plurality of nodes in the first non-inverting path; and coupling the second plurality of nodes in the first non-inverting path to the first plurality of nodes in the first inverting path; level shifting the first differential signal to provide a second differential signal having a second voltage range; and converting the second differential signal to a second single-ended signal having the second voltage range by: receiving the second differential signal with a load matching signal path; receiving the second differential signal with a second inverting signal path; coupling a third plurality of nodes in the second inverting path to a fourth plurality of nodes of the load matching signal path; and coupling the fourth plurality of nodes of the load matching signal path to the third plurality of nodes in the second inverting path.
