Abstract
A method and circuit for implementing a dual speed level shifter with automatic mode control, and a design structure on which the subject circuit resides are provided. A low speed level shifter and a high speed level shifter are used to provide a wide frequency range of operation. The circuit operates in one of a low speed mode or a high speed mode. The appropriate mode is selected automatically by detecting the frequency of the signal to be level shifted. When the incoming signal is slower than a reference frequency, the low speed level shifter is selected, and when the incoming signal is faster than the reference frequency, the high speed level shifter is selected.
