Due to the fruitful growth in the industry of medical devices especially in implantable medical devices, the research in this area has grown in the past few years. This paper presents an embedded processor platform chip suitable for medical applications requiring minimal power consumption. While this paper focuses on the key electronic features of implantable circuits and the integration of these features into silicon, it covers a proposed chip-architecture in design. This proposed design explores the partitioning of a chip, as well as the tradeoffs associated with design choices especially intelligent power management. Finally, it briefly covers the key attributes required in the silicon technology used for implementing implantable integrated circuit designs.INDEX TERMS Cardiac implant, neural implant, ultra low power (ULP), implantable medical device (IMD) system architecture, power management, signal processing, energy harvesting.

“…We consider if the performance variation of the GOFA caused by the oscillator error is tolerable, the performance variation of other detection algorithms caused by the oscillator error is also tolerable. In addition, the complexity of the GOFA is relatively low, so that it has been used in an embedded device after partial modifications [3,[18][19].…”

Implantable closed-loop epilepsy controllers require ideally both accurate epileptic seizure detection and low power consumption. On-chip oscillators can be used in implantable devices because they consume less power than other oscillators such as crystal oscillators. In this study, we investigated the tolerable error range of a lower power on-chip oscillator without losing the accuracy of seizure detection. We used 24 ictal and 14 interictal intracranial electroencephalographic segments recorded from epilepsy surgery patients. The performance variations with respect to oscillator frequency errors were estimated in terms of specificity, modified sensitivity, and detection timing difference of seizure onset using Generic Osorio Frei Algorithm. The frequency errors of on-chip oscillators were set at ± 10% as the worst case. Our results showed that an oscillator error of ± 10% affected both specificity and modified sensitivity by less than 3%. In addition, seizure onsets were detected with errors earlier or later than without errors and the average detection timing difference varied within less than 0.5 s range. The results suggest that on-chip oscillators could be useful for low-power implantable devices without error compensation circuitry requiring significant additional power. These findings could help the design of closed-loop systems with a seizure detector and automated stimulators for intractable epilepsy patients.
