Abstract
A compensation circuit and a method for compensating for process, voltage and temperature (PVT) variations in an integrated circuit (IC). The IC includes several functional modules, each of which includes a set of functional units, and generates an output signal in response to an input signal. The compensation circuit includes a code generator and a logic module. The code generator generates a digital code for each functional unit. The digital codes are based on phase differences between the input signal and the output signal. The logic module generates calibration codes based on the digital codes. The calibration codes compensate for the PVT variations in the corresponding functional units.
