Abstract :
Methods of CMOS resistance process voltage temperature variation detection and compensation are described. Two different approaches are proposed and comparative analysis is performed. The first solution makes use of an external precise resistor as a variation reference, while the second one uses reference clock frequency for the same purpose. Detection of variations is realized using the proposed digital and analog solutions. Efficiency of the suggested methods are tested and presented for high-speed CMOS systems.
