The simulation shows a very small
effect on the output characteristics of the DUT which can
be neglected. Some references in the literature proposed
that a diode be connected between CB and the DUT [3].
This diode needs to be reverse biased to remove the stray
capacitance effect of CB. However, a high power diode is
still needed, and so the stray capacitance of this diode
will be quite high similar to CB.
