Abstract
Operation of an internal voltage supply level (Vgg) of an IC is characterized over operating temperature or at a selected temperature to determine a temperature-equivalent internal voltage level. The internal voltage supply of the IC is set to the temperature-equivalent level, and the IC is tested at room temperature to screen for low-temperature defects or high-temperature defects.
