Abstract
An analog circuit automatic calibration system for calibrating an object circuit that is an analog circuit having a characteristic changing with an input set value. The system includes: a set value storage section for storing a value and outputting the value to the object circuit as the set value; a characteristic detection section for detecting the characteristic of the object circuit; a first characteristic change section for determining the set value so that the characteristic of the object circuit is optimized; a second characteristic change section for updating the set value so that the characteristic of the object circuit is maintained, using an algorithm different from that used in the first characteristic change section; and a selector for selecting either one of the outputs of the first and second characteristic sections to enable the selected one to be stored in the set value storage section.
