For the circuit shown in figure, true relation is

1. v_o1 = v_o2
2. v_o1 = – v_o2
3. v_o = 2v_o2
4. 2v_o1 = v_o2

Correct Option: B

At second stage input to both op-amp circuit is same. Upper op-amp circuit is buffer having gain, AV = 1. Lower op-amp circuit is inverting amplifier having gain

A_υ = -	R	= - 1
	R

∴ υ₀₁ = – υ₀₂
