1. A system for monitoring and compensating the performance of an operational circuit constructed on an integrated circuit chip, comprising:

  • one or more operational circuits constructed on the integrated circuit chip, wherein each operational circuit has one or more controllable operational circuit parameters;

    a process monitor module at least partially constructed on the integrated circuit chip, wherein the process monitor module generates at least one digitized sense signal indicative of one or more process-dependent integrated circuit parameters; and

    a controller coupled to the process monitor module and each operational circuit, wherein the controller includes;

    a monitoring processor that determines a value of one or more process-dependent integrated circuit parameters based on the at least one digitized sense signals, anda compensation processor that evaluates the performance of the one or more operational circuits based on the values of the one or more integrated circuit parameters, determines at least one adjustment to the one or more controllable operational circuit parameters, and generates a control signal to initiate the determined at least one adjustment.
