Abstract :
This paper describes a 5.8 GHz up-conversion mixer core based on a current-folded architecture and a 5 GHz differential emitter-coupled VCO utilizing a center-tapped inductor and a substrate shield. Both circuits are fabricated in a 0.8 μm 45 GHz fT SiGe-HBT technology and operate with a supply of -2.3 V to -3.3 V
