Original Abstract

This article presents the digitally adjustable current amplifier (DACA) and its analog behavioral model (ABM), which is suitable for both ideal and advanced analysis of the function block using DACA as active element. There are four levels of this model, each being suitable for simulation of a certain degree of electronic circuits design (e.g. filters, oscillators, generators). Each model is presented through a schematic wiring in the simulation program OrCAD, including a description of equations representing specific functions in the given level of the simulation model. The design of individual levels is always verified using PSpice simulations. The ABM model has been developed based on practically measured values of a number of DACA amplifier samples. The simulation results for proposed levels of the ABM model are shown and compared with the results of the real measurements of the active element DACA.

Tento článek představuje digitálně nastavitelný proudový zesilovač (DACA) a jeho analogový behaviorální model (ABM), který je vhodný jak pro ideální tak pokročilé analýzy funkčního bloku používajícího Daca jako aktivní prvek. K dispozici jsou čtyři úrovně tohoto modelu, z nichž každá je vhodná pro simulaci určitého stupně elektronických obvodů (např filtry, oscilátory, generátory). Každý model je prezentován pomocí schematického zapojení v simulačního programu OrCAD, včetně popisu rovnic, které představují konkrétní funkce v dané úrovni simulačního modelu. Návrh jednotlivých úrovní je vždy ověřen pomocí PSpice simulací. Model ABM byl vyvinut na základě prakticky naměřených hodnot několika vzorcích Daca zesilovače. Výsledky simulací pro návržených úrovní modelu ABM jsou zobrazeny a porovnány s výsledky reálného měření aktivního prvku DACA.
