AC COUPLE D PHOT ODIODE APPLICAT ION FOR
IMPROVE D DY NAMIC RANGE
AC coupling the photodiode current input to the AD8015 (Fig-
ure 17) extends fiber optic receiver overload by 3 dB while sacri-
ficing only 1 dB of sensitivity (increasing receiver dynamic range
by 2 dB). T his application results in typical overload of –4 dBm,
and typical sensitivity of –35 dBm. AC coupling the input also
results in improved pulse width modulation performance.
Careful attention to minimize parasitic capacitance at the
AD8015 input (from the photodetector input), R
AC
and C
AC
are
critical for sensitivity performance in this application. Note that
C

of 0.01
