Abstract

A fully integrated RFDAC based phase modulator in 40nm bulk CMOS is presented. To boost in-band linearity and the frequency range of operation, a harmonic rejection RFDAC architecture that suppresses the 3rd and 5th harmonics is proposed. The achieved frequency agility of the phase modulator is verified over a 0.6-2.5GHz range yielding EVM of -34.5dB and -36dB for an 18Mb/s and 75Mb/s GMSK signals, respectively. The power consumption of the proposed phase modulator is 33 mW at 2.4GHz.
