Abstract
Tema ovog rada je projektirati i izraditi jednostavno audio pojačalo pomoću operacijskog pojačala u ulaznom krugu i diskretnih bipolarnih tranzistora u izlaznom krugu. Operacijsko pojačalo ima namjenu predpojačala koje pojačava ulazni signal i prosljeđuje ga tranzistorima u izlaznom stupnju koji imaju glavnu ulogu u pojačanju signala. Analizirano pojačalo pripada klasi AB koja je po svojim svojstvima kombinacija klase A i klase B. Nakon provedenih analiza i računalnih simulacija, izrađene su tiskane pločice za pojačalo i pripadajuće napajanje. Provedena su mjerenja izrađenog sklopa i uspoređena s rezultatima simulacija. Za simulacije se koristi Advanced Design System, dok se za projektiranje tiskane pločice koristi KiCAD.
Abstract (english)
The main goal of the thesis was to produce a simple audio power amplifier that is designed with an operational amp in the input stage and a standard configuration of the bipolar junction transistors in the output stage. The input signal is gained by operational amplifier (that is used as a preamp) and then transferred to output transistors that play the main role in the output power gain. The analysis conducted in the thesis was for the AB class audio power amplifier that is basically the combination of the A and B class power amplifiers. Also, on the basis of the simulations that were ran throughout this thesis, a printed circuit board was designed, as well as the power source that goes along with it. Finally, the thesis presents measurements that were taken on the produced circuit board, and then conducts a detailed comparison with the mathematical analysis for the ideal amplifier.
