This letter presents a nonlinear model for carbon nanotube (CNT) Schottky diodes, integrating dc, small-signal, and large-signal parameters. A broadband equivalent model, spanning dc to 110 GHz, is ...

Although Fig. 2 is a simple circuit, it has the disadvantage of high forward voltage (V F) when the diode conducts. For example, the typical V F of a Schottky diode is ~0.4V and can result in ...
