His work primarily focuses on advancements in integrated circuit testing and electrostatic discharge (ESD) protection circuitry. Joordens has made significant contributions to the field, showcasing his expertise and innovative spirit.
Latest Patents
One of Joordens' latest patents is titled "Emulation and debug interfaces for testing an integrated circuit with an asynchronous microcontroller." This invention involves a method of testing a data transmission and reception system by sending a test signal from a transmitter to a receiver and analyzing the received signal. The method varies the duty cycle relationship between the test signal and the timing signal used by the receiver, allowing for the analysis of duty cycle distortion (DCD) as a form of embedded jitter insertion. This type of jitter can be measured relatively easily, enhancing the testing process.
Another notable patent is "Optimized ESD clamp circuitry." This invention discloses ESD protection circuitry within an integrated circuit that includes first and second sensor circuits. The first sensor circuit has a significantly greater resistive-capacitive (RC) time constant compared to the second sensor circuit. The design allows for effective activation of clamp transistors in response to detected ESD events, providing improved protection for integrated circuits.
