“…On-chip spiral inductors are widely used in RF integrated circuits (ICs) due to their low cost and ease of process integration. They are important components in VLSI circuits, such as voltage-controlled oscillators (VCO), filters or low-noise amplifiers (LNA).As a necessary tool for circuit design, equivalent circuit models of spiral inductors, using lumped RLC elements, efficiently represent their electrical performance for circuit simulation with other design components [1][2][3][4].…”

In this paper, a new circuit model for on-chip spiral inductors is presented. The model fits very well with the measured data in 0.13µm CMOS technology. Since the proposed model consists of frequency-independent lumped elements, it can be easily implemented in simulation program with integrated circuit emphasis (SPICE)-compatible simulators. The new model accurately captures series resistance and inductance over a wide frequency range, even beyond the self-resonant frequency.

“…A frequency-independent compact model with scalability is indispensible to inductor characterizations and circuit simulations [3]. The single-ʌ model does not satisfy this requirement due to its failure to capture the behavior of the effective series resistance(ESR) at high frequency [4]. The double-ʌ model, attributed to its more distributed nature, can model more features of an on-chip inductor [5], especilly the ESR.…”

A novel procedure to extract all parameters from a compact double-ʌ model for on-chip inductors has been presented. The major method used in the process is linear regression, which avoids iteration and complexity. The methodology presented here is used to extract parameters from the measured scattering matrices of symmetric inductors fabricated with a 0.18ȝm process. The comparisons between the predictions of the model based on the extracted parameters and the measurements demonstrate the effectiveness and accuracy of the proposed procedure over a broad frequency range even beyond the self-resonant frequencies(SRF)

In this paper, a new and simplified approach is proposed to model a radio frequency integrated circuit (RFIC) inductor in Si technology using Fuzzy Logic. An inductor structure made of a single‐layer metal ring fabricated on a silicon substrate is considered in the present analysis. The resistivity of the substrate layer, the thickness of SiO2 layer, and the frequency are considered as variable input parameters for the proposed model in order to calculate the effective inductance as output. The model results are then compared with the results obtained analytically using an equivalent circuit and reasonably good agreement is found within the scope of the model. © 2006 Wiley Periodicals, Inc.
