Abstract

V diplomskem delu je predstavljeno vezje in princip delovanja primerjalnika CMOS s samodejno kalibracijo, namenjenega uporabi v analogno digitalnih pretvornikih. V prvem delu je predstavljen razlog za kalibracijo ter različne metode avtomatskega ničenja ničelne napetosti. Opisana sta tudi termični šum in 1/f-šum ter metode, s katerimi je mogoče zmanjašati njun vpliv. V drugem delu je po delih opisano vezje primerjalnika in njegovo delovanje, nato so predstavljene simulacije, s katerimi se je vezje karakteriziralo in rezultati le teh. Na koncu je omenjenih tudi nekaj možnih izboljšav.

Secondary title: Design of CMOS comparator with automatic calibration
Secondary abstract: This work presents the circuit and operating principle of a self-calibrating CMOS comparator for use in analog to digital converters. The first part explains the need for calibration and presents various methods of automatic offset cancellation. Thermal noise and flicker noise (1/f noise) and ways to reduce their effects are also explained. In the second part, the individual parts that comprise the comparator circuit are presented and their function is explained. Simulations used to measure the comparators performance are explained and their results are shown. Lastly, some possible areas of improvement are mentioned.
