“…Previous work has focused on efficient optimization techniques of a pre-designed layout [9]- [11], [16], [17]. In contrast, this paper focuses on design reuse of filter layouts in LCP and enables scalability of circuit models for synthesizing layout geometries to meet different frequency specifications.…”

Let us assume that for a component , there exists a vector (11) where is the number of geometrical parameters associated with the component. Given a reference layout, its segmented components could be parameterized to generate a data set of component values with a varying geometrical parameter.…”

A fast and accurate layout-level synthesis and optimization technique for embedded passive RF components and circuits such as inductors and bandpass filters have been presented. The filters are composed of embedded inductors and capacitors in a multilayer liquid crystalline polymer substrate. The proposed approach is based on a combination of segmented lumped-circuit modeling, nonlinear mapping using polynomial functions, artificial neural network-based methods, and circuit-level optimization. Synthesis and optimization results of inductors for spiral/loop designs based on microstrip and stripline configuration are within 5% of data obtained from electromagnetic (EM) simulations. For RF circuits, the methodology has been verified through synthesis of 2.4-and 5.5-GHz bandpass filters with and without transmission zeros. Scalability has been shown over a range of 2-3 and 4-6 GHz, respectively, with bandwidth variation of 0.5%-3% of center frequency. The synthesized models are within 3%-5% of EM simulation data.Index Terms-Artificial neural networks (ANNs), filter synthesis, inductor optimization, liquid crystalline polymer (LCP), synthesis.

Abstract-We present a comprehensive microwave design framework for implementing the original, aggressive, implicit, and response residual space-mapping (SM) approaches through widely available software. General steps and tools for possible SM implementations are elaborated. Our presentation is a reference guide for microwave designers using the SM technique. An instructive "multiple cheese-cutting" example demonstrates the SM approach to engineering design and some possible pitfalls. For the first time, an ADS framework implements the SM steps interactively. A three-section transformer example illustrates the approach, step by step. A six-section -plane waveguide filter design emerges after four iterations, using the implicit SM and the response-residual space-mapping (RRSM) optimization entirely within the design framework. An RRSM surrogate is developed to match the fine (HFSS) model. We use sparse frequency sweeps and do not require Jacobians of the fine model. Index Terms-Computer-aided design (CAD), engineering optimization, filter design, parameter extraction (PE), space mapping (SM), surrogate modeling.
