Latest Patents

One of his latest patents is titled "Continuous self-calibration of internal analog signals." This invention describes a method and apparatus for monitoring and adjusting an analog signal of an operating circuit. The apparatus includes a control circuit, an analog-to-digital converter, and a comparator. The control circuit features an analog generator for generating the analog signal and an adjusting circuit for modifying the strength of the analog signal. The analog-to-digital converter receives the analog signal and converts it into a digital signal. The comparator then compares the digital signal's value to a predetermined value and generates a comparator signal. The adjusting circuit receives this comparator signal and adjusts the strength of the analog signal accordingly.

Another notable patent is "Implementation of a fusing scheme to allow internal voltage trimming." This invention provides methods and apparatuses for adjusting trim settings for internally generated voltages of an integrated circuit device. In one embodiment, the apparatus receives a target digital value for an internally generated voltage and compares it to the current digital value. If the difference exceeds an allowable threshold, the trim setting is adjusted based on this difference until the values align within the threshold.
