Abstract:
1. An apparatus, comprising: a first complement generation circuit configured to generate a first complementary signal responsive to a first input signal, the first complement generation circuit configured to operate in a first voltage domain powered at a first voltage potential; a first compensation circuit configured to generate a first compensated signal by compensating the first input signal for a delay corresponding to the first complement generation circuit, the first compensation circuit configured to operate in a second voltage domain powered at a second voltage potential, wherein the second voltage potential is different from the first voltage potential; a first phase mixing circuit configured to combine the first complementary signal and the first compensated signal to generate a first output signal; a second complement generation circuit configured to generate a second complementary signal responsive to a second input signal, the second complement generation circuit configured to operate in the second voltage domain powered at the second voltage potential; a second compensation circuit configured to generate a second compensated signal by compensating the second input signal for a delay corresponding to the second complement generation circuit, the second compensation circuit configured to operate in the first voltage domain powered at the first voltage potential; a second phase mixing circuit configured to combine the second complementary signal and the second compensated signal to generate a second output signal.
