摘要:
A design for a high speed differential voltage level shifter circuit arrangement utilizes both PFETs and NFETs controlled by inputs to determine the state of the outputs, which minimizes or eliminates contention on internal nodes when switching from one state to another. As a result, the design minimizes the adverse affects of mismatched NFET and PFET device strengths, and facilitates usage at high frequencies and for level shifting to a range of output voltage levels. The design is also adaptable for use in level shifting to higher or lower output voltages.
