“…For RF transformers, there are some models now obtainable in the literature. Rotella et al, [7] present an electrical model that takes into explanation the transformer and its parasitics, and Biondi et al, [8] and Wang et al, [9] also comprise analytical expressions to calculate some of its components. Likewise, El-Gharniti et al, [10] present an even more comprehensive model containing the equations to calculate each one of its elements.…”

“…Although these models are accurate, they are difficult to use with time-domain simulators. Other models are focused on finding frequency independent lumped elements to replace the frequency dependent impedance [7,8]. These models can be used in SPICE-like simulators; however, some of them have large number of elements and can be expensive in terms of computational time.…”

An equivalent electrical model of the skin effect in round wires is presented. The model includes a combination of frequency-independent resistors and inductors which is suitable to use in conventional time-domain simulators. Canonical ladder networks have been modified by including self and mutual inductances between tubes. The elements and the circuit topology are defined according to the fields in the wire and they are also based on a decomposition of the wire in successive concentric tubes. Moreover, an extra inductor that captures the external inductance of the winding is also included in the network. The impedance of this network matches the exact analytical impedance of the round wire over a frequency range that depends of the number of elements. The network can be used for transient analysis as well as for providing steady-state response for repetitive input waveforms. The effect of the thicknesses of the tubes and the number of tubes on the accuracy of the model is analyzed. The measured impedance of a flat multi-turn coil wound with a round wire is compared with impedance calculated by using the proposed network and good agreement has been observed.

“…In the design of analog RFICs, models of spiral inductors are necessary to predict, simulate and optimize the responses of circuits. Several models of spiral inductors have been reported such as the simple-p [3][4][5][6][7], T-models [8,9], double-p [10][11][12][13], and enhanced simple-p [14][15][16][17]. Enhanced simple-p and double-p networks have been introduced to model high parasitic effects such as proximity effects and substrate coupling between the two ports of the spiral.…”
