This paper deals with the design and simulations of a 4-bit flash analog-to-digital asynchronous converter designed in 0.35 mum CMOS technology. The input voltage signals of a range of 1.6 V are converted to binary numbers based on flash method. Analog part of the project, which is made using full-custom technique, contains 17 comparators. The two extra comparators indicate when input signal is out...
The paper describes design and testing of the monolithic asynchronous analog-to-digital converter fabricated in CMOS AMS 0.35 µm technology. Two basic tests are applied to calculate error parameters of the ADC: code test to obtain a static characteristic and input-output test to measure the SNR (signal-to-noise), the ENOB (effective-number-of-bits), and propagation times to determine maximum conversion...
