A Simple Parameter Extraction Method of Spiral On-Chip Inductors

An accurate hierarchical electromagnetic-circuit technique for statistical analysis of RF circuits

“…The present paper focuses on spiral inductors and their use in microwave amplifiers. In a system where no variability is modeled, well known techniques exist to derive accurate circuit models for the passives modeled by field solvers and to incorporate them in SPICE simulations [2]. The scenario changes drastically when the system is subjected to variability under process variations.…”

“…These element values are determined by means of an optimization procedure from the sparameters obtained through field solver simulations [2]. The circuit element values are in general correlated.…”

“…Physpack [2] is the full-wave solver used for the extraction of the port parameters of the inductors. PhysPack is based on fast multilevel tree-based methods for accelerated integral equation solution and therefore provides exceptional speed and memory performance, ideal for use in this application.…”

Optimization Ofspiral Inductor With Different Inner Diameters

“…It needs to design suitable accurate multilayer integrated circuits by selecting suitable substrate material along with geometric parameters (width, space and inner diameter)of the models. The different circuit level models have been proposed by the researchers [6][7][8][9][10][11][12].…”

A unified analytical and scalable lumped model of RF CMOS spiral inductors based on electromagnetic effects and circuit analysis

“…Analytical extraction techniques based on network analysis [3][4][5] and fitting procedure [14,[20][21][22] have been also investigated, and are more efficient. Indeed, these methods are related to the physical phenomena which occur in spiral inductors.…”
