GMSK modulation of subharmonic injection locked oscillators

This paper presents theoretical results on phase modulation of injection locked oscillators. Experimental results on a 2-GHz fifth subharmonic injection locked oscillator (SBILO) integrated in a 0.35-/spl mu/m BiCMOS STMicroelectronics technology are presented. Measured phase error added by the SBILO once locked by a GMSK modulated signal is negligible.
