Title: Innovations of Roman Procházka

Introduction

Roman Procházka is a notable inventor based in Struharov, Czech Republic. He has made significant contributions to the field of current sensing technology. With a total of 3 patents to his name, Procházka continues to push the boundaries of innovation in his field.

Latest Patents

His latest patents include a "Hall plate current sensor having stress compensation." This invention involves methods and apparatus for a voltage-driven Hall plate current sensor integrated circuit (IC) package. The design features a die that includes a Hall plate with a lateral epi resistor. A gm amplifier receives an output voltage from the Hall plate, while a front-end amplifier processes the output of the gm amplifier. Additionally, a compensation circuit is integrated to address stress on the die that affects the resistance of the Hall plate. This circuit includes a lateral epi resistor coupled to a constant current for compensating for piezoresistive stress in the Hall plate.

Another significant patent is the "Sensor architecture for correcting thermally-induced linearity error." This current sensor comprises a substrate and a conductor disposed on or adjacent to the substrate. It features one or more sensing elements formed on the substrate, which generate signals in response to a magnetic field associated with the conductor. The electronic circuitry on the substrate is designed to produce a second signal indicative of the electrical current level through the conductor. This circuitry includes multiple instances of components and mixing circuitry to create a mixed signal.
