Harmonic Generation by Nondegenerate P-N Junction Varactor Diodes
Active and Passive Electronic Components, 1997 This paper deals with the large-signal analysis of nondegenerate p-n junction varactor diodes. Expressions are obtained for the harmonics of the varactor diode current when driven by a sinusoidal voltage signal. The special case of relatively small input
