Application
Transimpedance amplifiers are commonly used in receivers for optical communications. The current generated by a photodetector generates photo voltage, but in a nonlinear fashion. Therefore the amplifier has to prevent any large voltage by its low input impedance and generate either a 50 Ohm signal to drive a coaxial cable or a voltage signal for further amplification. Note that the most linear amplification is current amplification by a bipolar transistor, so you may want to amplify before the impedance conversion.

Famous quotes containing the word application:
“Preaching is the expression of the moral sentiment in application to the duties of life.”
—Ralph Waldo Emerson (1803–1882)
“May my application so close
To so endless a repetition
Not make me tired and morose
And resentful of man’s condition.”
—Robert Frost (1874–1963)
“There are very few things impossible in themselves; and we do not want means to conquer difficulties so much as application and resolution in the use of means.”
