CMOS Mixer and VCO with Balun for ZigBee Health Monitoring and Communications

The proposed radio frequency integrated circuit development, intended for use in 2.4-GHz signal receiver has been product in tsmc 0.18-µm CMOS technology. The integrated 2.4-GHz frontend signal receiver consists of the 3
^rd
order Gm-C passive bandpass loop filter with graph convolutional neural networks (GCNs) algorithm, double balance mixer with active balun and supercapacitors finetune voltage - controlled oscillator (VCO) as probe conductive experimental on wafer station. The proposed results meet 2.4 GHz wireless near field communication requirements for ZigBee and health monitoring.
