A micro-fabrication process is proposed to realize high-thickness spiral inductors for the remote powering of implantable biosensors through inductive link. The process is suitable for different substrates, such as silicon and Pyrex, and enables the fabrication of the receiving inductor directly on the implantable system. The use of Ordyl Alpha960 is explored to achieve high-thickness structure...

Inductive power transfer is the most common method for transferring power to implantable sensors inside human body. For good inductive coupling, the inductors should have high inductance and high quality factor. But the physical dimension of the receiver inductor cannot be large due to biomedical constraints. Therefore, there is a need for small size and high inductance, high quality factor ind...

This paper presents an area-effective bandwidth enhancement technique using interwoven inductors. Inductive peaking is a common practice for bandwidth enhancement, however the area overhead of inductors is a serious issue. We implement six or four inductors into an interwoven inductor. Furthermore parasitics of the inductors can be reduced. The proposed inductor is applied to a laser-diode driv...

This study proposes a method which consists of High step up DC-DC converter with a coupled inductor for distributed generation system. Theoretically the conventional boost converter provides high step up voltage gain but in practical it is limited by reverse recovery problem of diode, effective series impedance of inductors and capacitors and switching losses. High charged current and conductio...

Wireless power transfer via inductive link is becoming a popular choice as an alternate powering scheme for biomedical sensor electronics. Spiral printed circuit board (PCB) inductors are gaining attractions for wireless power transfer applications due to their various advantages over conventional inductors such as low-cost, batch fabrication, durability, manufacturability on flexible substrate...

This paper presents the design and modeling, fabrication and characterization of suspended spiral inductors on silicon substrate. The substrate materials underneath the inductor coil are removed by micromachining process to reduce the substrate loss which enables high frequency operation.

In the current trend toward portable applications, highintegrated inductors are gaining a lot of importance. Using thin-film multilayer or multichip-module-deposition technology, highcircular inductors for RF and microwave applications may be integrated efficiently. Their quality factors may go up to over 100. In this paper, an accurate analytical model for such multiturn circular spiral induct...

In this paper, a new single-cell hybrid switched inductor DC-DC converter is proposed to demonstrate the verification of ultra-high voltage gain in renewable energy applications (REA).
