Abstract
An integrated circuit includes at least a first and second compensation circuit that compensate for process, temperature, and other variable conditions that affect circuit performance. A compensation select circuit is coupled to selectively enable each of the first and second compensation circuits at respective first and second time periods to control a voltage on the input/output terminal to substantially equal a reference voltage and thereby determine appropriate compensation setting.
