IMPLANTABLE COMMUNICATION SYSTEM STARTER SYSTEM AND METHODS

摘要

A starter circuit for an electronic device includes a rectifier circuit having an input coupled to an antenna; a Schmidt trigger coupled to the rectifier circuit; a pulse timer circuit coupled to receive pulses from the Schmidt trigger and configured to measure pulse characteristics to determine whether the pulses are part of a valid startup sequence and to generate a reset signal if the pulses are not part of a valid startup sequence; and a counter having first and second inputs coupled to outputs of the pulse timer circuit, the counter configured to output a signal to initiate power-on of a component of the electronic device a when its count value reaches a predetermined value.
