Voltage-controlled oscillators (VCOs) are critical components for signal generation and frequency selection in RF/microwave transceivers. Recently, there has been considerable interest in monolithic integration of inductance-capacitance (LC) tank oscillators for highly integrated RF transceivers [1]. Technologies such as Si complimentary metal-oxide-semiconductor (CMOS) and Si/SiGe BiCMOS are o...

In this paper, we propose and evaluate a novel design of a lightly doped drain and source carbon nanotube field effect transistor (LDDS-CNTFET) with a negative differential resistance (NDR) characteristic, called negative differential resistance LDDS-CNTFET (NDR-LDDS-CNTFET). The device was simulated by using a non equilibrium Green’s function method. To achieve this phenomenon, we have created...
