Transimpedance Operational Amplifier Circuit
A transimpedance amplifier (TIA) converts an input current into a proportional voltage, typically using an inverting op-amp with a feedback resistor (Rf). TIAs are conceptually simple: a feedback resistor (RF) across an operational amplifier (op amp) converts the current (I) to a voltage (VOUT). It's also a common building block that helps explain the performance and stability limits of many other op-amp circuits.
