Abstract
A detector for detecting an occurrence of a current strength of interest (e.g. zero current) of a current of a signal to be sensed includes a magnetoresistive structure and a detection unit. The magnetoresistive structure varies a resistance depending on a magnetic field caused by the current of the signal to be sensed. Further, the detection unit generates and provides a current detection signal indicating an occurrence of the current strength of interest based on a detected magnitude of the varying resistance of the magnetoresistive structure.
Claims20
A voltage converter comprising:
- an input configured to receive a voltage signal to be converted;
- a magnetoresistive structure configured to vary a resistance depending on a magnetic field caused by the voltage signal to be converted or a processed signal obtained by processing the voltage signal to be converted;
- a detector configured to generate and provide a current detection signal indicating an occurrence of a current strength of interest within the voltage signal to be converted or the processed signal obtained by processing the voltage signal to be converted based on a detected magnitude of the varying resistance of the magnetoresistive structure;
- and
- a converter configured to covert the voltage signal to be converted or the processed signal obtained by processing the voltage signal to be converted to a converted voltage signal based on the current detection signal.
