|a ESN mreža uvodi se kao temeljna sastavnica za modeliranje ponašanja nelinearnih integriranih sklopova u uvjetima velikog signala budući da može modelirati nelinearne odnose između vremenskih signala opaženih u simulacijama integriranih sklopova. Predstavljen je adaptivni algoritam za uzorkovanje nelineranog ponašanja integriranih sklopova u vremenskoj domeni koji omogućuje izgradnju ESN modela koji modeliraju široko područje rada modeliranih sklopova.
Predstavljen je model nelinearne impedancije temeljen na ESN mreži. Model omogućuje izgradnju zamjenjivih ponašajnih modela integriranih sklopova koji se koriste u okruženju za simulacije otpornosti integriranih sklopova na vođene smetnje prema standardu IEC-62132-4 Direct RF Power Injection (DPI). Model se primjenjuje na modeliranje naponske reference s odvojnim stupnjem koja se sastoji od triju podsklopova. Dan je pregled nelinearnih efekata te metodologija za određivanje preciznosti modeliranih vremenskih signala. Analizira se stabilnost predstavljenih ponašajnih modela koja je podijeljena na stabilnost statičke radne točke, stabilnost u uvjetima malog signala te stabilnost početnog tranzijenta.
Principi ponašajnog modeliranja primijenjeni su na probleme iz područja ESD i EMC. Predstavljen je model mjernog postava za pulsiranje prijenosne linije te ponašajni model elementa za zaštitu od elektrostatskih izboja s negativnim dinamičkim otporom. Predstavljen je ponašajni model I2C stezaljke integriranog sklopa koji omogućuje simulaciju reradijacije radiofrekvencijskog signala zbog harmoničke distorzije u magnetski spregnutom bežičnom sustavu.

|a The echo state network (ESN) is presented as the building block for the behavioural modelling of integrated circuits. The ESN is able to model the nonlinear relationships of time-domain signals observed in integrated circuit simulations. An adaptive algorithm for sampling the nonlinear behaviour of integrated circuits in the time-domain is proposed, that enables building ESN models that cover a wide range of operation of the modelled circuit.
A nonlinear impedance model based on the echo state network is proposed. The model enables building interchangeable behavioural models of integrated circuits in the conducted immunity simulation environment according to the IEC-62132-4 Direct RF Power Injection (DPI) standard, and it is applied to a buffered voltage reference integrated circuit that consists of three subcircuits. An overview of nonlinear effects observed in the conducted immunity simulations of the modelled circuit is presented, and the methodology for evaluating the accuracy of the modelled time-domain waveforms is introduced. The stability of the presented behavioural models is analysed, including the DC operating point stability, the small-signal stability, and the initial transient stability.
The behavioural modelling principles are also applied to modelling applications in ESD and EMC area. A lumped-distributed model of a transmission line pulsing setup is presented, including a behavioural model of an ESD protection device that exhibits snapback. The behavioural model of an I2C pad of an industrial integrated circuit is presented that enables simulating the RF re-radiation due to RF harmonic distortion in a magnetically coupled wireless system.
