We report a low power ASK IF receiver for short-range wireless systems,which includes an AGC loop that compensates the channel attenuation and an ASK detector. A novel current-limited transconductor and feed-forward d...
A CMOS fully-differential 2.4GHz ∑-△ frequency synthesizer for Gaussian minimum shift keying (GMSK)modulation is presented. A pre-compensation fractional-N phase-locked loop(PLL)is adopted in the modulator.The t...
A 2GHz differentially tuned CMOS monolithic LC-VCO is designed and fabricated in a 0.18μm CMOS process. The VCO has a 16.15% tuning range (from 1. 8998 to 2. 2335GHz) through a combination of analog and digital tun...
