majority carrier conduction, it is not subject to junction di‐
ode forward and reverse recovery transients due to minority
carrier injection and stored charge. Satisfactory circuit ana‐
lysis work may be performed by using a model consisting
of an ideal diode in parallel with a variable capacitance.
