Q. Explain Current-to-Voltage Amplifier?
The basic circuit is shown in Figure, which is similar to that of an inverting amplifier. The - input is connected directly to a current source supplying current iS. Node X is a virtual ground, so that
iS = - vo / Rf
Hence
vo = - RfiS
which shows that the degree of amplification depends on the value of Rf.
