Hello Folks,
It would be nice to tie a TIA into the cathode to get positive polarity
output in one of my circuits. That would mean the (critical) RF path
also needs to be connected to cathode. The anode would then get the bias.
On all PDs I looked at so far neither anode nor cathode are connected to
the housing. Is this customary or should I assume that cathode could be
grounded or have higher capacitance to the enclosure on some models?
