    Abstract: This paper presents the design and analysis of a high-performance fully-integrated 0.18μm CMOS voltage-controlled oscillator (VCO) with low supply voltage and low dc power consumption. To enhance the transconductance (gm) of MOSFETs and negative conductance (-Gm) of a cross-coupled pair, the device size of the nMOS cross-coupled pair is enlarged. F... Show More

    Abstract: We have argued that the nature of surface potential variation with gate voltage of AlN/GaN/AlGaN Double Heterojunction Field Effect Transistor (DHFET) is no different from that of the conventional GaAs/AlGaAs HEMT devices. Necessary simulated band diagrams have been presented to justify our claim and we have also proposed a non-linear expression fo... Show More
