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...
This paper describes two types of PEEC-based methods for the analysis of planar spiral inductors. One approach is a high-level distributed network method (DNM), while the second is based on a relatively simple equivalent SPICE circuit. The inductors are printed on lossless, grounded ceramic substrates and the metallization is assumed to have finite conductivity, but is infinitesimally thin, so ...
While previous studies on substrate coupling focused mostly on noise induced through drain-bulk capacitance, substrate coupling from planar spiral inductors at radio frequency (RF) via the oxide capacitance has not been reported. This paper presents the experimental and simulation results of substrate noise induced through planar inductors. Experimental and simulation results reveal that isolat...
This paper presents the design of square spiral inductor on FR4 substrate for different number of turns. Various simulations based on the incipient models were done by varying geometric parameters. Here, we vary the number of turns from 5 to 9 and find out their effect on Inductance (L), Quality factor (Q) and Self resonant frequency (SRF). The development of inductors for RF telemetry applicat...
Introduction: Recently, the bandpass LC current mirror has been used to increase conversion gain by combining the output differential currents at the high frequency [1, 2]. However, the passive inductors employed in the LC current mirror always occupy large chip area. In this work, the passive inductors in the LC current mirror are replaced by the active inductors consisting of the common-colle...
This paper presents a chip-level integration of radio-frequency (RF) microelectromechanical systems (MEMS) air-suspended circular spiral on-chip inductors onto MOSIS RF circuit chips of LNA and VCO using a multi-layer UV-LIGA technique including SU-8 UV lithography and copper electroplating. A high frequency simulation package, HFSS, was used to determine the layout of MEMS on-chip inductors wi...
Silicon integrated circuit spiral inductors and transformers are analyzed using electromagnetic analysis. With appropriate approximations, the calculations are reduced to electrostatic and magnetostatic calculations. The important effects of substrate loss are included in the analysis. Classic circuit analysis and network analysis techniques are used to derive two-port parameters from the circu...
An efficient modeling technique and a novel CAD tool for the accurate prediction of the performance of integrated inductors and transformers is presented. This generic and process-independent approach generates lumped-element models that easily plug into the RF IC design flow. Their accuracy is established through comparisons with measurements of numerous fabricated inductor structures. This pa...
