Kurzbeschreibung:
Die Vorlesung behandelt den Entwurf von Phasenregelkreisen (PLL) auf System- und Transistorebene. Amplitudenrauschen und Phasenrauschen von Signalen werden in PLL-Bausteinen modelliert und diskutiert. Es werden verschiedene PLL-Architekturen wie ganzzahlige N- und gebrochene N-PLLs behandelt.
