Numerical approach for calculating the response of a p-n junction capacitor to a ramp signal

The transient response of a junction capacitor to a linear ramp voltage input is calculated from the basic nodal equations using a predictor-corrector method of integration. Advantages of the numerical methods are discussed. The dependence on normalizing factors on contact potential, dc bias, and on slope and magnitude of the input waveform is indicated. Some representative response curves for abrupt, linearly graded, and hyperabrupt junction capacitors are presented.
