Title: Michael Keller: Innovator in Integrated Circuit Technology
Introduction
Michael Keller is a prominent inventor based in Heidelberg, Germany. He has made significant contributions to the field of integrated circuit technology, holding a total of 5 patents. His work focuses on enhancing the functionality and efficiency of electronic devices through innovative circuit designs.
Latest Patents
Among his latest patents, Keller has developed a self-trim and self-test circuit for on-chip values. This self-trim circuit employs a least significant bit (LSB) offset to determine the optimal digital value for trimming a circuit under trim (CUT). Additionally, it is designed to self-test both the digital and analog components of the self-trim circuitry, effectively detecting any digital stuck-at fault conditions. A state machine is utilized to manage a digital stack, coupling digital trim data to the CUT and reading the output of a comparator circuit, which indicates when the appropriate digital trim value has been achieved. Once determined, this value is stored in nonvolatile memory.
Another notable patent is the adjustable integrator using a single capacitance. This invention features an integrating amplifier on an integrated circuit (IC) that includes a feedback loop utilizing an external device as an integrating capacitor. An additional feedback loop has been incorporated to provide extra current to the amplifier's input, allowing for an increased input range of charge measurement without the need for another external capacitor or pad.
