This article describes a new method of wave form transformation through the
use of a nonlinear capacitor. Two specific examples, the transformation of
a sinusoidal wave form to a triangular wave form and vice versa are discus
sed in detail. A method of obtaining this nonlinear capacitor, by having a
suitable doping profile in a metal-oxide-semiconductor capacitor is also de
scribed. (C) 1999 American Institute of Physics. [S0034-6748(99)00208-7].
