Latest Patents

Hansen's latest patents include innovative solutions for identifying board connections for differential receivers. This invention features testing arrangements that detect proper DC-coupled board connections on the input legs of a differential receiver. The implementation includes a first test receiver that is AC-coupled to the connection between the first input/output (I/O) pad and the differential receiver's positive input. Additionally, a second test receiver is coupled to the connection between the second I/O pad and the differential receiver's negative input. This design protects the test receiver input from DC voltages and includes a high-pass filter arrangement that generates data to detect proper connections. This approach is less susceptible to noise compared to conventional low-pass RC filter arrangements.

Another significant patent by Hansen is an apparatus for determining capacitance variation in an integrated circuit. This apparatus includes at least two capacitances and a stimulus provided to them. A first logic element is coupled to the stimulus and the capacitances, configured to switch state upon a state transition of the stimulus when the capacitances differ by a predetermined amount. This invention enhances the understanding of capacitance variations in integrated circuits.
