Different Gains in Transimpedance Amplifiers

The gain, bandwidth, as well as current and voltage offsets change with different types of sensors, requiring different configurations of transimpedance amplifiers.OverviewIn, a transimpedance amplifier (TIA) is a to converter, almost exclusively implemented with one or more (opamps). The TIA can be used to amplify the current output of In the circuit shown in Figure 1, a sensor (represented as a current source) such as a photodiode is connected between ground and the inverting input of the opamp. The other input of the opamp is also connected to ground,. The frequency response of a transimpedance amplifier is inversely proportional to the gain set by the feedback resistor.
