Latest Patents
One of Tony Coffey's latest patents is titled "Probeless DC testing of CMOS I/O circuits." This innovative method allows for the measurement of I/O input and output circuitry of a CMOS chip without the need to physically probe the chip. The technique utilizes output driver transistors to provide marginal voltages for testing input circuits. These transistors are segmented into portions, with one portion supplying a representative 'on' current to a test bus connected to a current comparator circuit within the chip. This method enables the measurement of both leakage and 'on' current of the driver transistors. The output from the current comparator circuit can be linked to a test scan register or a test output, allowing for digital retrieval of test results. This testing technique is also applicable to other semiconductor devices, showcasing its versatility and importance in the industry.
