While we used to call this a "current-to-voltage converter," which it is indeed, it&x27;s also sometimes referred to as a "transimpedance amplifier," where the "gain" or "transimpedance" is equal to.

In its simplest form a transimpedance amplifier has just a large valued feedback resistor, R f. The gain of the amplifer is set by this resistor and because the amplifier is in an inverting configuration, has a value of -R f. There are several different configurations of transimpedance amplifiers, each suited to a particular application.

A transresistance amplifier converts an input of current to an output of voltage. It is also called a voltage to current converter or V to I converter. It is called transresistance because the efficiency of the amplifier is measured in units of resistance. The analysis will be done assuming ideal op-amp characteristics. The current entering the op-amp terminals is zero..
