P. Heymann et al., A PHYSICS-BASED MODEL OF HYPERABRUPT VARACTORS FOR NONLINEAR TRANSMISSION-LINE APPLICATIONS, International journal of microwave and millimeter-wave computer-aided engineering, 7(4), 1997, pp. 278-288
This article presents a physics-based varactor-diode model for exponen
tially graded doping profiles, The capacitance-voltage characteristic
and the bias dependence of the series resistance are discussed in deta
il. The model is validated by frequency and time domain measurements o
n Ga is varactors. The optimum design for nonlinear transmission line
(NLTL) applications is discussed. (C) 1997 John Wiley & Sons, Inc.
