Feedback Analysis and Design of RF Power Links for Low-Power Bionic Systems
TLDR
This paper presents a feedback-loop technique for analyzing and designing RF power links for transcutaneous bionic systems, i.e., between an external RF coil and an internal RF coil implanted inside the body, and proposes an optimal loading condition that maximizes the energy efficiency of the link.
A Low-Power Asynchronous Step-Down DC–DC Converter for Implantable Devices
TLDR
A fully integrated asynchronous step-down switched capacitor dc-dc conversion structure suitable for supporting ultra-low-power circuits commonly found in biomedical implants and Experimental test results confirm the expected functionality and performance.
A high-resolution hybrid randomized modulation scheme for switched-mode DC-DC converters
Switched-mode dc-dc converters are routinely employed in the power supply section of low-power electronic systems, such as biomedical implants, to convert a supply voltage from one voltage level to

TLDR
Buck converters and switched-capacitor converters may not be suitable for biomedical implants due to the limited space inside the implants, which can only accommodate a few small discrete components, and an alternative approach based on a direct conversion of the induced AC voltage to a regulated DC voltage is proposed.

  • 2010
TLDR
The efficiency formula is shown to fit remarkably well the efficiency data of a number of representative low power and low voltage commercial dc-to-dc converters regardless of their topology as well as custom designed high power, high voltage converters.
The 128-Channel Fully Differential Digital Integrated Neural Recording and Stimulation Interface
TLDR
The fully differential 128-channel integrated neural interface was validated in in vitro recording of a low-Mg2+/high-K+ epileptic seizure model in an intact hippocampus of a mouse and had a noise efficiency factor of 5.6.
A Wireless Integrated Circuit for 100-Channel Charge-Balanced Neural Stimulation
TLDR
The design of an integrated circuit for wireless neural stimulation, along with benchtop and in - vivo experimental results, is presented, able to activate motor fibers to produce muscle twitches via a Utah Slanted Electrode Array implanted in cat sciatic nerve, and to activate sensory fibers to recruit evoked potentials in somatosensory cortex.
Development and Implantation of a Minimally Invasive Wireless Subretinal Neurostimulator
