Abstract
A compensation circuit and a method for detecting and compensating for process, voltage, and temperature (PVT) variations in an integrated circuit. The integrated circuit includes plural logic modules that include PMOS transistors and NMOS transistors. The compensation circuit includes first and second functional modules, which generate first and second calibration signals. The first and the second calibration signals are used to compensate for the PVT variations in PMOS and NMOS transistors.
