This paper presents the design considerations for thin-film magnetic power inductors for integrated voltage regulator (IVR). Optimum design parameters for solenoid inductors are arrived at that maximize key performance metrics such as quality factor, inductor efficiency, inductance density, and operation frequency. A fabrication approach to integrate the solenoid inductor with thin-film magnetic material...
In this paper, an equivalent three port scalable Inductor model has been developed for symmetric octagonal spiral inductors. The scalable inductor model is able to achieve good match for two port with center-tap connected to ground, three port differential and three port single-ended structures. Adjustable parameters include the number of turns (N), inner diameter (D), width (W) and spacing (S) of...
In this paper, we have developed equivalent scalable inductor models for symmetrically octagonal spiral inductors. Adjustable parameters include number of turns (Nturn), inner diameter (D), width (W) and spacing (S) of inductors with models being scaled over a wide specification range. A complementary frequency independent scalable 4-PI model are presented for accurate modeling When compared with...
In this work, the design of a single ended low-noise amplifier (LNA) dedicated for multi-band orthogonal frequency-division multiplexing (MB-OFDM) Band Group-1 ultra-wideband (UWB) band is described. It achieves a flat gain from 2 to 5 GHz of 17 dB while drawing a current of 15.9 mA from a 1.2 V supply. The circuit has been implemented in 90 -nm CMOS technology and features a minimum noise figure...
