Medical implant, e.g. pacemaker, comprises primary and secondary digital signal processors, analogue and digital circuits, and power source

摘要

A medical device comprising primary and secondary digital signal processing units, one or more analogue and digital circuits, and a power source, is new. A medical device comprises primary and secondary digital signal processing units, one or more analogue and digital circuits, and a power source. The processing units operate at different frequencies and the circuits can carry out at least one function. The primary and secondary frequencies are such that the voltage requirement is less for both processors than for one alone. The voltage control circuit produces at least a second supply voltage which can be supplied to one or more analogue circuits.
