  • Patent number: 11828625
    Abstract: The described techniques address issues associated with hybrid current or magnetic field sensors used to detect both low- and high-frequency magnetic field components. The hybrid sensor implements a DC component rejection path in the high-frequency magnetic field component path. Both digital and analog implementations are provided, each functioning to generate a DC component cancellation signal to at least partially cancel a DC component of a current signal generated via the high-frequency magnetic field component path. The hybrid sensor provides a high-bandwidth, high-accuracy, and low DC offset hybrid current solution that also eliminates the need for DC decoupling capacitors in the high-frequency path. A modification is also described for implementing a Sigma-Delta (??) quantization noise reduction path to reduce the quantization noise and to improve accuracy.

  • Patent number: 11831148
    Abstract: A method for operating an electronic switch is described hereinafter. According to one exemplary embodiment, the method (for an electronic switch in the switched on state) comprises detecting whether there is an undervoltage condition at a supply voltage node and providing an undervoltage signal which indicates an undervoltage condition. The method further comprises switching off the electronic switch if the undervoltage signal indicates an undervoltage condition and switching (back) on the electronic switch if the undervoltage signal no longer indicates an undervoltage condition. If the undervoltage signal indicates an undervoltage condition during a switch-on process of the electronic switch, the electronic switch is switched off again and switching back on is prevented for a defined period of time, irrespective of the undervoltage signal. Moreover, a corresponding circuit is described.
