Abstract

Rad se sastoji od pregleda literature o negativnim pretvornicima impedancije i njihovoj
realizaciji pomoću idealnih i realnih operacijskih poja;ala. Obavljena je teoretska
analiza idealnog i realnog negativnog RLC kruga realiziranog naponskim negativnim
pretvornikom impedancije koji u pozitivnoj povratnoj vezi ima otpor, induktivitet
i kapacitet. Realno pojačalo korišteno u ovom radu je modelirano izrazom s dva pola
koji, kako je prikazano u dodatku, vrlo dobro opisuje ponašanje realnog pojačala, barem
do frekvencije 1 MHz. Simulacije nagativnog RLC titrajnog kruga su obavljene
u programskom paketu Advanced Design System - ADS i vjerno se slažu s teoretskom
analizom. Analiza i simulacija su upotpunjeni mjerenjem eksperimentalnog kruga razvijenog
na Zavodu za radiokomunikacije i rezultati mjerenja se također slažu s teoretskom
analizom.

Abstract (english)

In this thesis is shown a brief literature review of negative impedance converters
and its construction using ideal and real operational amplifiers. Theoretical analysis
of negative RLC tank circuit was done. The circuit was constructed using voltage
negative impedance converter with resistance, inductivity and capacity in positive feedback.
Amplifier used in the negative converter was analyzed both as being ideal
and being an amplifier with a two-pole response. It is shown that two-pole transfer
function describes used amplifier very well, at least up to the frequency of 1MHz. Simulations
of negative RLC tank circuit were performed in commercial circuit-theory
simulator Advanced Design System - ADS and they agree with theoretical analysis.
Both analysis and simulations were completed with the measurements on the negative
RLC experimental demonstrator, previously developed at the Department of Wireless
Communications and results also agree with theoretical analysis.
