answer= vin+vos

Figure 4 shows the circuit symbol and the equivalent representation of an op-amp with
nonzero input offset voltage (Vos). In the closed loop applications of 'op-amps with
nonzero input offset voltage', we use the following assumptions:
in = i, = 0A
• Vn = Vpos = Vp + Vos
• temperature of each op-amp is assumed to be constant and input offset voltage
drift is ignored
Assume that we build the circuit in Figure 5 by using an opamp with a nonzero input
offset voltage (Vos). Which one of the following is the equation for the output (Vout) of
the circuit in Figure 5?
