Abstract :
A demodulator has been designed which consists of a 3.6 GHz VCO, a 3.8 mA current-mode divider for the I/Q generation, and two single-ended input double-balanced mixers. The IC consumes 10 mA at 1.8 V, and has -114 dBc phase noise at 100 kHz offset, 40 dB image rejection, 14 dB DSB noise figure and 8.5 dBm IIP3.
