Minimum
Sampling
Rate
And
Maximum
Gain
If
the
sampling
rate
is
too
slow
the
dSEVC
becomes
unstable.
This
is
because
the
long
current
‐
passing
period
charges
the
membrane
potential
past
the
desired
potential
before
the
clamp
has
an
opportunity
to
take
a
new
sample
of
potential
and
adjust
the
current
accordingly.
The
larger
the
cell
membrane
capacitance
(C
m
)
the
slower
the
sampling
rate
(f
s
)
that
can
be
