<p>Impulsni generator predstavlja jedan od najvažnijih delova bežičnog<br />primopredajnika. Pored toga što treba da generiše signal čiji<br />spektar zadovoljava odgovarajuću spektralnu masku, generator treba da<br />bude što jednostavniji, zauzima malu površinu i ima malu potrošnju.<br />Naučni doprinos ove doktorske disertacije predstavlja sedam novih<br />konfiguracija ultra-širokopojasnih impulsnih generatora<br />projektovanih u CMOS tehnologiji, od kojih su tri fabrikovane u<br />0,18 μm UMC CMOS procesu. Prvi dizajn je zasnovan na principu<br />kombinovanja kratkotrajnih impulsa, sledeća tri sadrže ring<br />oscilator, naredna dva impulsna generatora koriste princip<br />filtriranja, dok poslednje novo rešenje obezbeđuje BPSK kodovanje<br />korišćenjem dva ring oscilatora.</p> / <p>Pulse generator is one of the most important parts of a wireless transceiver.<br />Besides generating a signal which spectrum has to satisfy corresponding<br />spectral mask, the pulse generator should have topology as simple as<br />possible, consume low power and occupy low die-area. Scientific contribution<br />of this dissertation are seven novel IR-UWB pulse generator architectures<br />designed in CMOS technology of which three are fabricated in 0.18 μm UMC<br />CMOS process. The first design is based on combining very short pulses, the<br />next three contain a ring oscillator topology followed by two pulse generators<br />that use the filtering approach, while the last new solution enables BPSK<br />modulation by employing two ring oscillator topologies.</p>
