Abstract—A wideband phase-locked loop (PLL)-based G/FSK
transmitter (TX) architecture is presented in this paper. In the pro-
posed TX, the G/FSK data is applied outside the loop; hence, the
data rate is not constrained by the PLL bandwidth. In addition, the
PLL remains locked all the time, preventing the carrier frequency
from drifting. In this architecture, the G/FSK modulation signal
is generated from a proposed Sigma-Delta modulated Phase Ro-
tator
