Abstract

In this paper closed-form expressions are presented for the current components in a CNT-based p-n junction diode resulting from a multisinusoidal input voltage. The expressions obtained, in terms of the modified Bessel functions, are simple and can be used for calculating the amplitudes of the fundamental, harmonics and intermodulation (mixing) current components in the CNT-based p-n junction diode. Using these expressions the performance of the CNT-based p-n junction diode excited by an equal-amplitude two-tone was studied in detail. The results obtained show that the amplitudes of the harmonic and mixing components are strongly dependent on the DC bias voltage, the series resistance and the ideality factor of the p-n junction diode.
