A METHOD FOR MANUFACTURING A CALIBRATION DEVICE

A method for manufacturing a calibration device for an active circuit on a chip, comprises: providing an active circuit that is capable of exhibiting a desired electrical characteristic; and providing a calibration mechanism on-chip with the active circuit. The calibration mechanism generates a control output and comprises a device under test (DUT) configured as a replica of at least one segment of the active circuit, and which generates a test output that causes finite adjustments to the control output, based on a comparison of the electrical characteristics exhibited by the DUT with a known electrical characteristic. The method further comprises: attaching to each control input terminal of the active circuit a corresponding control output from the calibration mechanism. The control output of the calibration mechanism dynamically adjusts control input applied to devices of the active circuit to force the active circuit to exhibit the desired electrical characteristic.
