TIAs are conceptually simple: a feedback resistor (RF) across an operational amplifier (op amp) converts the current (I) to a voltage (VOUT) using Ohm''s law, VOUT = I × RF. In this series of blog posts, I will
The overall effect of negative feedback in the voltage follower is to cause the output voltage to settle on a value that is equal to the voltage at the noninverting input terminal. When the input signal has variations that are slow relative to the op-amp''s dynamic performance, we don''t notice this settling action.

In electronics, a transimpedance amplifier (TIA) is a current to voltage converter, almost exclusively implemented with one or more operational amplifiers (opamps). The TIA can be used to amplify the current output of Geiger–Müller tubes, photo multiplier tubes, accelerometers, photodetectors and other sensors (that are modeled well as a current source) into a usable voltage.
