(1) The AC method is a frequency domain measurement. A 10-MHz ac voltage signal of known dc offset and amplitude of 82.5 mV are
applied to the pin under test. The imaginary component of the complex current is measured and used in the equation:
C = I
im
/ (2 × π × F × V
IN
) where I
im
= imaginary component of input current, V
IN
= magnitude of input voltage, and F = frequency.
