Abstract
MEMS pezoelektrički rezonatori konstruirani su kako bi pomogli pri detekciji ultrazvučnih emisija koje dolaze iz biljke sa ciljem optimizacije potrošnje vode u poljoprivredi. Gredice MEMS piezoelektričkih rezonatora prilikom detekcije emisije generiraju signal male amplitude koji je potrebno pojačati kako bi bio korišten u ugradbenim računalnim sustavima. Projektiranje pojačala počinje s izborom pojačala po specifikacijama te simulacijom, a najboljim se pokazalo pojačalo proizvođača Texas Instruments OPA4354. Za to pojačalo projektirana je električka shema i dizajnirana je tiskana pločica te je pojačalo funkcionalno ispitano u laboratoriju. Rezultati pokazuju da pojačalo daje željene karakteristike pri pojačanju A = 51 te za veće iznose kapaciteta na ulazu pojačala.
Abstract (english)
MEMS piezoelectric resonators are constructed for detection of ultrasonic emissions from plants with an end goal of optimizing water usage in agriculture. MEMS piezoelectric resonator beams are generating small signals during emission detection, and those signals need to be amplified for usage in embedded systems. Amplifier design starts with choosing operation amplifiers that meet predefined specification followed by simulation of those amplifiers. The best characteristics were found in operation amplifier OPA4354 manufactured by Texas Instruments. After the amplifier had been chosen, electric circuit was constructed and PCB produced, amplifier was tested in laboratory. Results show that amplifier has the best characteristics for gain A = 51 and for bigger amount of capacitance at the input of amplifier.
