  • Common mode rejection ratio test system and method
    Patent number: 11209459
    Abstract: An electronic device test system includes a contactor having probe pairs with first and second conductive probes to couple to a respective conductive feature of a packaged electronic device or wafer die region. The system also includes a test circuit having a voltage source to provide a common mode voltage signal; a first buffer with a first input coupled to an output of the voltage source, an output coupled to a first conductive probe of a first probe pair, and a second input coupled to a second conductive probe of the first probe pair; and a second buffer with a first input coupled to the output of the voltage source, an output coupled to a first conductive probe of a second probe pair, and a second input coupled to a second conductive probe of the second probe pair.
    Type: Grant
