HIGH FREQUENCY OPERATION
Since current flow in a Schottky rectifier is the result of
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.
(See Figure 12.)
Rectification efficiency measurements show that opera-
tion will be satisfactory up to several megahertz. For ex-
ample, relative waveform rectification efficiency is ap-
proximately 70 percent at 2.0 MHz, e.g., the ratio of dc
power to RMS power in the load is 0.28 at this frequency,
whereas perfect rectification would yield 0.406 for sine
wave inputs. However, in contrast to ordinary junction di-
odes, the loss in waveform efficiency is not indicative of
power loss; it is simply a result of reverse current flow
through the diode capacitance, which lowers the dc output
voltage.
