Abstract
U radu se predlaže jednostavan projekt impulsno analogno-digitalnog pretvarača (ADC) u 0,18 μm CMOS tehnologiji. Taj bi se pretvarač trebao koristiti u senzoru temperature, koji daje izlaz analognih podataka u rasponu od 360 mV do 560 mV. Sustav se sastoji od tri glavna bloka: threshold inverter quantization (TIQ) - komparatora, kodnog uređaja (kodera) i parallel input serial output (PISO) registra. Svrha je projekta dobiti impulsni ADC s malim gubitkom energije, malih dimenzija i kompatibilnim sa senzorima temperature. Ovom bi se metodom trebala podesiti dužina svakog kanala tranzistora u svrhu pronalaženja razlike u ulaznom naponu pretvarača na TIQ komparatoru. Projektom se predviđa ulazni raspon od 285 do 600 mV i izlaz rezolucije 6-bita. Površina čipa projektiranog ADC je 844,48 × 764,77 μm2 a gubitak energije iznosi 0,162 μW uz napajanje od 1,6 V.
