Patent ID: 7570071

Claim:
A method for calibrating an inverter circuit, said method comprising: receiving a test voltage output from a device under test (DUT), said DUT configured as a replica of a segment of the inverter circuit that is desired to be calibrated to exhibit a specific electrical characteristic and said DUT receiving a control input; comparing the test voltage output to a known reference voltage; when the comparing yields a first result indicating the test voltage output meets a pre-determined criteria, providing the control input to the inverter circuit that is the same as the control input being provided to the DUT; and when the comparing yields a second result indicating the test voltage does not meet the pre-determined criteria, said method further comprises: dynamically adjusting said control input by a finite amount; and providing the adjusted control input to the DUT via a feedback loop, wherein said control input is continually adjusted by said finite amount until the comparing yields the first result.
