Scope
Transistor capacitances are usually measured on two-terminal capacitance or impedance bridges. When
the capacitances are in the low picofarad ranges, this two terminal measurement is not very accurate or
reproducible. The stray capacitances to ground are of the same order of magnitude as the quantities
being measured and vary with mechanical changes in the surrounding ground planes.
