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. ; This paper proposes a simple design of a flash analog-to-digital converter (ADC) in 0,18 μm CMOS technology. This ADC is expected to be used within a temperature sensor, which provides analog data output having a range of 360 mV to 560 mV. This system consists of three main blocks: the threshold inverter quantization (TIQ)-comparator, encoder and parallel input serial output (PISO) register. The design goal is to get a flash ADC with low power dissipation, small size and compatible with the temperature sensors. The method is proposed to set each of the transistor channel length, for finding out the threshold voltage difference of the inverter each on the TIQ comparator. The design has an input range of 285 to 600 mV and 6-bit resolution output. The chip area of the designed ADC is 844,48 × 764,77 μm2 and the power dissipation is 0,162 μW with 1,6 V supply voltage.
