Circuit arrangement for producing logic signal for use with medical implant device such as pacemaker or defibrillator that comprises number of voltage sources and switches to reduce implant power consumption

摘要

Device comprises a capacitor (682) connected to a bus in the implant device and connected to a first potential. In addition the system comprises N voltage sources (V1-VN) connected to N switches (S1-SN) that branch off a bus that connects to a first switch (684) that is in parallel with the capacitor and is in between capacitor and N voltage sources. A command device connects to the switches to control them. An independent claim is made for a similar device, but based on an array of capacitors in parallel.
