The circuit of Figure 3 overcomes this problem by AC-coupling the current transformer to the transimpedance amplifier. Note that the capacitor value required depends on the application; capacitor value affects the low-frequency response, and by resonating with the transfomer inductance, it can produ...
The Transimpedance amplifier is a current to voltage converter that is designed with an active component like anoperational amplifierto change the input current to a proportional output voltage. It is also achievable to design an active current to voltage converter with active components like IGBTs, ...

Figure 1. For resistor values less than 20MΩ, this simple transimpedance amplifier is acceptable for use with some current sources. Resistor values above 20MΩ are notoriously difficult to apply. For applications requiring a transimpedance above 20MΩ, consider the circuit of Figure 2. The output...
This reference design implements and measures a complete 120MHz wide bandwidth optical front end comprising a high speed transimpedance amplifier, fully differential amplifier, and high speed 14-bit 160MSPS ADC with JESD204B interface. Hardware and software are provided to evaluate the (...) ...
Figure 9. Programmable transimpedance amplifier. The circuit in Figure 10 avoids these problems by using two switches in every transimpedance leg. Although this requires twice as many switches, the on resistance of the switches on the left is within the feedback loop, so the output voltage depend...
