METHODS AND APPARATUSES FOR DUTY CYCLE PRESERVATION

摘要

Methods and apparatuses are disclosed for preserving duty cycle at voltage domain boundaries. One example apparatus includes a complement generation circuit configured to generate a complementary signal responsive to an input signal. The complement generation circuit is configured to operate in a first voltage domain. The apparatus also includes a compensation circuit configured to generate a compensated signal by compensating the input signal for a delay corresponding to the complement generation circuit. The compensation circuit is configured to operate in a second voltage domain. The apparatus also includes a phase mixing circuit configured to combine the complementary signal and the compensated signal to generate an output signal.
