Title: Architectures for TIA design Post by t_stoll on Aug 9th, 2006, 11:11pm Hi all - I have to design a CMOS TIA which has to operate up to 400MHz with an AC coupled input (comming from an photo diode) and an input noise current density spec of <= 1pA/sqrt(Hz). This noise spec seems quite taff! Any idea what kind of architecture I could choose ? I also have not seen any TIA differentially connected to the photo diode AC coupled. The only papers I find have a DC coupling connection (single ended).. Best regards, tOM |
