摘要: An implantable medical device (IMD) is disclosed having measurement circuitry for measuring one or more currents in the IMD, such as drawn from various power supply voltages. Such are measured without disrupting normal IMD operation, and can be telemetered review. Switching line with current being temporarily opened a time period to disconnect voltage powered. A across capacitance parallel when switching again closed at end of period, drawing charged during this period. The average by determined using difference voltages, known capacitance, between measurements.
