Introduction: When switching power supplies of the buck family (forward converter, full and half bridge, etc.) have more than one output as shown in Figure 1, separate filter inductors (L1,L2) are normally used in each output. These independent inductors hurt performance by decoupling and isolating the outputs from each other. Dynamic cross regulation is very poor and several other major proble...

Design and Implementation of highly efficient Reflective type phase shifters (RTPS) at 60GHz has been proposed in this work. Low loss cost effective design which utilizes less chip area is proposed. At high frequencies, to improve the efficiency of the communication system highly directional high gain antennas have to be used. Phase shifters are one of the most important elements in phased arra...

The paper deals with reliability evaluation procedure of thick film inductors manufactured by various techniques. Thick film inductors belong to the specific electronic passive components, which properties are known as a component „tailored“according to the application, structure and construction. Evaluation methodology principle of thick film inductors issues from entities of standardized reli...

We present a frequency-tunable, compact loop antenna which consists of a transmission line on a ground plane, two shorting posts, and two inductors which are serially connected between the posts and the edge of the transmission line. By properly choosing the inductance of the inductors, the operating frequency of the antenna can be controlled without seriously sacrificing fractional bandwidth. ...

The advancement of CMOS technology led to the integration of more complex functions. In the particular of wireless transceivers, integrated LC tanks are becoming popular both for VCOs and integrated filters [1]. For RF applications the main challenge is still the design of integrated inductors with the maximum quality factor. For that purpose, tapered, i.e., variable width inductors have been p...

An average model of SEPIC converters with coupled inductors was developed and verified against cycle-by-cycle simulations. The model can be used as-is by any modern circuit simulator to run steady state (DC), large signal (Transient) and small signal (AC) analyses. The inductors coupling coefficient, incorporated as a parameter in the model, can be varied from zero to almost unity. Zero couplin...

Radio frequency (RF) tunable inductors have a major role in current situation where compact designs with high performance are demanded. The capability of the tunable inductors, to tune the inductance with high or proper quality factor (Q-factor), has been a good advantage in the tunable systems to the designers rather than to use the tunable capacitor which exhibit poor reliability and require ...

Designing integrated inductors for RF applications is quite a challenging task due to the necessity of minimizing the parasitic effects arising from using today’s technologies. The multiplicity of non-ideal effects to be minimized makes imperious the use of optimization-based design methodologies. In this paper a model-based optimization methodology is considered as a way of offering the design...

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...
