The Cúk converter, which has voltage buck and boost ability, offers high flexibility as an interface device for solar panels. In addition, current ripple can be more reduced because of two input and output inductors at both sides. This paper presents a new application of current-variable inductors in a Cúk converter that reduces the size and capacity of storage elements. Because of two inductor...

The inductor is a substance that is found in the embryo. It fu..11ctions to evoke cellular proliferation and cellular differentiation. The inductor is more active in some areas of the embryo than in other areas. These active induction areas may be called induction fields. The inductor vvas dis covered in the embryo. Spemann, Vo gt , and Na.ngold made significant contributions to the field of ex...

This paper presents a novel d is tor t ion compensation technique using an active inductor. First, we describe the input-reflection-coefficient characteristics of a GaAs MESFET active inductor when input power increases. We show that the inductor exhibits positive amplitude deviation and negative/positive phase deviation as the input power increases when the biases of the FETs are set appropria...

On-chip inductors are widely used in many modern RFICs. Realization of high-Q inductors often requires extra back-end processing and costly chip area. Accurate modeling and thorough optimization of the inductor are required for best performance. In this paper we present a scalable broadband inductor model. The model supports multiple symmetric and asymmetric inductor layouts and has been incorp...

This paper present a pulse width modulation non-isolated buck converter using PID controller. The buck converter constituted by one Gto, one inductor, one capacitor, one diode and one load resistor. In this the buck converter connected to the PID controller, PID controller calculate an error value as the difference between a measured process variable and a desired set point. The proportional P ...

A post-CMOS maskless dry etch process has been developed to fabricate MEMS structures compatible with commercial low-k copper interconnect processes. The micromachining in the copper low-k process enables the fabrication of an RF inductor with quality factor of 12 at 7.5 GHz and a variable capacitor operating up to 3GHz. Reduction of fluorine concentration in the plasma for the low-k dielectric...

This review of design principles for implementation of a spiral inductor in a silicon integrated circuit fabrication process summarizes prior art in this field. In addition, a fast and physics-based inductor model is exploited to put the results contributed by many different groups in various technologies and achieved over the past eight years into perspective. Inductors are compared not only b...
