Abstract

Naslov ovog završnog rada je ''Višestupanjsko asimetrično napajano pojačalo izvedeno diskretnim elementima''. Nad sklopom provodimo statičku i dinamičku analizu. Dinamičkom analizom ispitujemo pojačanje zajedničkog signala i pojačanje diferencijskog signala. Računamo i faktor potiskivanja koji pokazuje kvalitetu diferencijskog pojačala. Dobivamo da je faktor potiskivanja ρ=80 dB, odnosno 10000, a što je veći ρ to je diferencijsko pojačalo kvalitetnije. Pokazali smo kako povratna veza utječe na... More pojačanje pojačala, također i frekvencijske odzive. Less

Abstract (english)

The title of this bachelors thesis is ''Multistage and asymmetrically powered amplifier made with discrete elements. We conduct static and dynamic analysis over the circuit. With dynamic analysis we examine common and differential signal amplification. We calculate the common-mode rejection ratio which shows the quality of Differential amplifiers. We find that the common-mode rejection ratio ρ = 80 dB, or 10000, and with the higher ρ the differential amplifier has more quality. We have shown... More how the feedback loop affects the amplifier gain, also the frequency response. Less
