Quad Capacitance
Capacitance of Schottky diode
quads is measured using an
HP4271 LCR meter. This
instrument effectively isolates
individual diode branches from
the others, allowing accurate
capacitance measurement of each
branch or each diode. The
conditions are: 20 mV R.M.S.
voltage at 1 MHz. Agilent defines
this measurement as “CM”, and it
is equivalent to the capacitance of
the diode by itself. The equivalent
diagonal and adjacent capaci-
tances can then be calculated by
the formulas given below.
In a quad, the diagonal capaci-
tance is the capacitance between
points A and B as shown in the
figure below. The diagonal
capacitance is calculated using
the following formula
