Abstract

U početnom dijelu rada slijedi pregled osnovnih prednosti CFOA sklopova. Nabrojani su veći Slew-rate, odvojenost GBP-a, potreba za manjim brojem pasivnih elemenata,… Nakon nabrajanja osnovnih prednosti CFOA sklopa, slijedi realizacija GP2 filtra. Prvo je prikazan GP2 filtar realiziran pomoću OA, a iza toga slijede realizacije uz pomoć CCII+ sklopova. Prikazana su dva načina realizacije, jedan upotrebom isključivo CCII+ sklopa (zahtjevniji način). Traži se veći broj elemenata od kojih su mnogi viška, međutim realizira prijenosnu funkciju identičnu onoj kod GP2 filtra s OA, a drugi upotrebom nekoliko različitih vrsta CCII sklopova čime se postiže značajna ušteda CCII sklopova i pasivnih elemenata. Za kraj je kao primjer realiziran nisko propusni filtar 8. reda po Buterworthu, te simuliran u programu za analizu električnih krugova PSpice.

Abstract (english)

In the introduction of this work an overview of the basic advantages of CFOA circuits is presented. It is explained theirs higher Slew rate, possibility of the GBW-product separation, the realization using a fewer number of passive elements, ... After enumerating the basic advantages of the CFOA circuit, the realization of the GP2 filter follows. First, the GP2 filter is realized using OA, and then the realizations with the use of CCII+ circuits follow. There are two ways of realization, one using CCII+ circuit only (a more demanding way). In this realization, larger number of elements is needed, many of them are redundant, nevertheless it realizes the transfer function identical to that of the GP2 filter with OA. The other realization using several different types of CCII circuits, achieves significant savings of CCII circuits and passive elements. In the end, as an example, the low-pass, 8th-order Buterworth filter is designed, and simulated in the PSpice electric circuit analysis program.
