I-V
Converter
Block
Diagram
The
I-V Converter
is essentially
an integrator
composed of
an
operational
amplier
and
a
capacitor
.
When
current Ix
ows into
the integrator
,
the
current
charges
the
capacitor
.
As
a
result,
the
integrator
outputs a
negative going
ramp of
which
slope
is
0
I
x
C
.
The
current
Ix can
be
obtained
by
0
C
1
v
1
t
,
where
1t
is
a
certain
time
interval,
and
1v
is the
output voltage
drop
for
this
interval.
Capacitor
C,
which
is
called
the
range
capacitor,
determines
the
applicable
measurement
range
in practical integrator
.
