SYSTEMS AND METHODS MITIGATING TEMPERATURE DEPENDENCE OF CIRCUITRY IN ELECTRONIC DEVICES

摘要

Methods and systems for compensating for temperature variation in the performance of electronic circuits and systems are disclosed. In some embodiments, the systems are configured to store compensation parameters determined in calibration, where the compensation parameters are used by the systems to modify performance. In some embodiments, the systems are part of an automatic test equipment (ATE) system.

1. A method of using an electronic device, the device comprising a voltage measurement unit configured to generate a measurement value indicative of a voltage, wherein the measurement value is based partly on a temperature, the method comprising:
applying a first voltage to the device; setting the temperature to each of multiple temperature values; storing a first plurality of measurement values indicative of the first voltage for the multiple temperature values; generating a first relationship, the first relationship being between the first measurement values and the temperature; generating a parameter for a compensation function based on the first relationship, wherein the compensation function is dependent on temperature, and wherein the compensation function is configured to be used to determine a compensated voltage value based on a test voltage which is measured at a measurement temperature and which is received by the voltage measurement unit; and storing the generated parameter.
