This study presents a high efficiency inductive power link aiming for the implanted biomedical devices. Improving the efficiency of the inductive link is critical, since the overall efficiency of a remote powering system is dominated by the inductive link. Therefore, the proposed system utilizes the resonance phenomenon which enables maximum energy transfer between objects which are at resonance....
This paper describes a receiver system design for impulse-radio ultra-wideband (IR-UWB) that operates at two carrier frequencies—3.494 and 3.993 GHz—with a 10-Mbps data rate. To reduce the power consumption of the front-end amplifiers, a super-regenerative architecture is used. An integrated circuit, implemented in a CMOS 0.18- technology and operating with a 1.5-V power supply, exhibits...
This paper presents how to design an inductive link and a method to find an efficient inductive link for transcutaneous powering and communication for a knee prosthesis. The best place for the coils and the most efficient coil pairs are proposed by utilizing an accurate and easy inductor model. The optimal number of turns and the sizes of the primary and the secondary coils are found and the coils...
