Q. Explain Current-to-Current Amplifier ?

The circuit given in Figure is to amplify a current fed to the input of the op amp. Applying KCL at Y,

i1 + iS = io

Since i1 = - vY /R1, Equation becomes

iS - vYR1 = io

Because X is a virtual ground, vY =-iSRf . Hence Equation becomes

The current gain is then given by
