1. A power domain change circuit comprising:
a transfer circuit operating in a first power domain, and configured to receive an input signal to output a first intermediate signal;
an inversion circuit operating in the first power domain, and configured to invert the first intermediate signal to output a second intermediate signal;
an averaging circuit operating in a second power domain, and configured to invert the first intermediate signal and non-invert the second intermediate signal to generate a correction signal; and
a combination circuit operating in the second power domain, and configured to combine the second intermediate signal and the correction signal to generate an output signal.
