Englische Kurzfassung:
A key issue which precedes the digitization of Phase-
Locked Loops (PLLs) is the realization of proper phase
to digital converters. Phase comparators in All-Digital
PLLs (ADPLLs) apply a quantization on the phase error
which represents the control variable of the PLL. This
paper introduces simulative analysis of the properties
and requirements of full-digital phase comparators regarding
the quantization resolution. Effects defining the
realization requirements for multi-mode applications are
investigated.
