A new integrated magnetic full wave dc/dc converter1 that provides flexible transformer design by incorporating an independent output inductor winding is introduced. The transformer is implemented on a traditional three-leg magnetic core. The inductor winding can be separately designed to control the output current ripple. The cross-sectional area of the inductor core leg can be reduced dramati...

In this paper, an integrated passive device (IPD) inductor modeling is demonstrated. The IPD technology is a system in package (SiP) solution where passive devices with high quality can be fabricated on a chip and then connect with another circuit chip by using flip-chip micro-bump bonding. For an RF circuit simulation, the IPD inductor model is built and verified from the measurement results. ...

This paper investigates a current mode active inductor. In the proposed active inductor, three current mirrors have been connected to each other to realize the negative feedback. This active conductor has a two layer transistor structure. A 4.257 GHz, 1.2-V power supply non-inductive LC negative resistor oscillator, base on two of the proposed active inductors, is demonstrated. Keywords-active ...

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 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...

This paper presents the design of a multilevel pyramidically wound symmetric (MPS) inductor structure. Being multilevel, the MPS inductor achieves high inductance to area ratio and hence occupies smaller silicon area. The symmetric inductor is realized by winding the metal trace of the spiral coil down and up in a pyramidal manner exploiting the multilevel VLSI interconnects technology. Closed ...

This paper presents the use of a new structure of active inductor named cascoded flippedactive inductor (CASFAI) in a T-type high-pass tunable output matching network of a class-E RF power amplifier (RFPA) to control the output power and enhance the efficiency. The designed CASFAI behaves as an inductor in the frequency range of 0-6.9 GHz, and has reached to a maximum quality factor of 4406, in...
