Integration of energy-recycling logic and wireless power transfer for ultra-low-power implantables

摘要: This paper presents an integration of energy-recycling logic circuits with a wireless power transfer receiving module for ultra-low-power applications, such as transcutaneous biomedical implantables. In the prototype design, one inductive coil implanted inside body receives and supplies following electronics. While part loading is composed conventional CMOS logics, rest implemented circuits. Energy-recycling associated adiabatic operation achieve excellent energy efficiency by transferring recycling between digital blocks along signal propagation. The required AC further lead to natural therefore obviate need rectifier that contributes substantial loss. As proof concept, finite-impulse-response filter designed in 90-nm process. Simulation results show 59.3% reduction compared static counterpart.
