A fully integrated 0.13-mum CMOS RFIC PLL transmitter for GFSK/GMSK modulation at 2.4-GHz ISM band is presented. A bandpass SigmaDelta direct digital frequency synthesized (BPSADDFS) reference oscillator is developed to provide a wideband RF PLL with a frequency modulated signal. The RF PLL-transmitter uses a single-bit bandpass SigmaDelta modulated(More)
