Abstract
Systems and methods for circuits that self-correct errors due to variations in fabrication processes, voltages, and temperature (PVT), as well as input timing errors. In an exemplary embodiment, a method for improving output signal quality in a complementary logic circuit is provided. An n-type transistor in the complementary logic circuit is digitally enabled or biased with a first variable power supply. A p-type transistor in the complementary logic circuit is digitally enabled or biased with a second variable power supply, providing a voltage different from that of the first variable power supply, to mitigate a difference in the switching times between the p-type transistor and the n-type transistor.
