Current Controlled Voltage Sources:

The circuit is illustrated in Figure, since, non inverting input terminal is connected to ground, because of infinite gain and negative feedback, the inverting input terminal is forced to have ground potential (virtual ground) because of which V_m = 0.

Also, because infinite Z_in, no current is drawn by the op-amp input terminal.

Hence,

I_in  = 0 - V₀ / R₀

or         V₀  = - R₀ I_in

and the circuit acts as an inverting CCVS.

Non-inverting CCVS can be obtained in two different ways as illustrated in Figure

Figure: Non-inverting CCVS Structures

(i)   By cascading an inverting VCVS with the circuit of a inverting CCVS, so that

                               V₀  =- (R₀  I_in)(-R₂ /R₁)   = + (R₀ R ₂)I_in or

 (ii) By putting a NIC with in the feedback path of the inverting CCVS, the analysis for which gives

                                                 V₀        = +( R₁ R₀ / R₂)I_in
