Non-idealities such as finite op-amp gain and parasitic capacitances introduce deviations. In practice, ZT is frequency-dependent due to the amplifier''s bandwidth limitations and the RfCf network''s pole.
Transimpedance amplifiers are typically used to amplify very small currents. This means that a large gain, which leads to a large Rf, is needed. Aside from the inherent bandwidth limitations imposed in
