An ideal opamp circuit and its input waveform are shown in the figures given below. The output waveform of this circuit will be

Correct Option: D

V₀ = + V_sat , if V₊ > V–
= – V_sat , if V₊ < V_–

V_A =	1	V₀ =	V₀
	1 + 2		3

V_in ≃ V_A ≤ 2 (for V₀ = 6, upto t₂)
After t₂, V_out = – 3V_A

At t = t₄ , V_A =	1	(– 3) = – 1V (for V₀ = – 3, after t₄)
	3

Hence after t₄, V_out = 6V
