Abstract: The present disclosure involves methods, systems and computer program products for calibrating a measuring device to ensure that its overall accuracy is improved. The method includes generating a profile of a first and second device. The profiles may be generated using one or more profiling scenarios. The method includes comparing a profile of the second device against a profile of the first device, automatically adjusting the profile of the second device such that it substantially matches the profile of the first device, and transferring the adjusted profile to the second device. The transferring of the adjusted profile to the second device causes the second device to provide substantially the same output as the first device in response to the same input parameter.

Abstract: A delay is measured through an array of transistors by selecting one transistor in the array; and applying a clock signal to the selected transistor. An output of the selected transistor is applied to a first input of a logic gate and a second clock signal based on the clock signal is applied to a second input of the logic gate. An output of the logic gate indicates a difference in arrival times of the signals at the two inputs. A clock signal can be applied to the selected transistor and a variable delay circuit. An output of the selected transistor is applied to a data input of a latch while an output of the variable delay circuit is applied to a clock input of the latch. The delay applied by the variable delay circuit is adjusted until a predefined transition is detected. The delay variation among the transistors can be obtained.
