8.3 Differential TIA with 0-V Biased Photodiode

The circuit in Figure 8-7 can be used for a differential TIA with 0-V reverse bias across the photodiode. The VICM loop should be disabled in this configuration since the loop can only source or sink DC current. Any DC current generated by the photodiode in the configuration shown will be differential in nature.
