Voltage level shifting with reduced timing degradation

A method, comprising:

• receiving, at a first input, a first input signal that varies in accordance with a first voltage domain in accordance with a first mode of operation;
• receiving, at a second input, a second input signal that varies in accordance with a second voltage domain in accordance with the first mode of operation, wherein the first voltage domain is different than the second voltage domain;
• and
• generating, at an output, a first output signal that varies in accordance with the second voltage domain in accordance with the first mode of operation, wherein the first output signal is based on the first and second input signals.

An apparatus, comprising:

• a voltage domain splitter including an input configured to receive a first signal in a first voltage domain, a first output configured to generate a second signal in a second voltage domain, and a second output configured to generate a third signal in a third voltage domain, wherein the second and third signals are based on the first signal;
• a first edge alignment circuit configured to generate a fourth signal in the third voltage domain based on the second signal and a complementary of the third signal;
• and
• a second edge alignment circuit configured to generate a fifth signal in the third voltage domain based on a complementary of the second signal and the third signal.
