Abstract
A multimode receiver can include on or more of an over-voltage protection circuit or a high frequency mode switch. As such, some embodiments of a multi-mode receiver includes a rectifier; a high frequency circuit coupled to the rectifier; a low frequency circuit coupled to the rectifier; and a switching circuit coupled to disable at least a portion of the low frequency circuit while the multi-mode receiver operates in high frequency mode. In some embodiments, the multimode receiver further includes a high-voltage protection circuit coupled to the high frequency circuit that detunes the high frequency circuit when a high-voltage condition is detected.
