Title: Frank Dornseifer: Innovator in Voltage Regulation Technologies

Introduction

Frank Dornseifer is a notable inventor based in Freising, Germany. He holds a total of eight patents, showcasing his contributions to the field of voltage regulation and integrated circuit design. His innovative work has significantly impacted the technology landscape.

Latest Patents

One of his latest patents is titled "Digital LDO Passgate Rotation." This system includes a digital controller in a voltage regulator, along with a passgate array comprising two or more passgate transistors. The passgate array is designed to provide load current to a load, while the digital controller activates and deactivates each passgate transistor based on an error signal. This error signal is derived from the difference between the output voltage of the voltage regulator and a programmed voltage. Additionally, the digital controller operates the passgate transistors in response to clock cycles.

Another significant patent is "Bandgap Reference Voltage Failure Detection." This integrated circuit features a bandgap voltage reference circuit with a corresponding output. The bandgap failure detection circuit compares the present value of the reference voltage to a model value, asserting a bandgap fail signal when the present value falls below a certain threshold. This mechanism allows the integrated circuit to reset while ensuring critical operations can continue during the reset process.
