Abstract
An electronic system includes an integrated circuit, powered by a first voltage, with a first device provided therein; a detection device coupled to the first device to detect an output deviation of the first device attributed to process, voltage and temperature (PVT) effects; and a compensation device coupled to the detection device, adjusting the first voltage in response to the output deviation and outputting the first voltage to the integrated circuit to compensate for the PVT effects. The electronic system further comprises a conversion device, coupled between the detection device and the compensation device, to generate an indication signal corresponding to the output deviation for the compensation device to adjust the first voltage. In addition, the compensation device may compare and amplify a difference between a voltage level of the indication signal and a reference to linearly adjust the first voltage for compensating for the PVT effects.
