For each op-amp in Figure P14.57, the input bias current is \(I_{B}=2 \mu \mathrm{A}\) at \(T=25^{\circ} \mathrm{C}\), the input offset current is \(I_{O S}=0.2 \mu \mathrm{A}\) at \(T=25^{\circ} \mathrm{C}\), the input bias current temperature coefficient is \(20 \mathrm{nA} /{ }^{\circ} \mathrm{C}\), and the input offset current temperature coefficient is \(5 \mathrm{nA} /{ }^{\circ} \mathrm{C}\).

(a) Find the worst-case output voltages \(v_{O 1}\) and \(v_{O 2}\) due to the average input bias currents at \(T=25^{\circ} \mathrm{C}\).

(b) Find the worst-case output voltages \(v_{\mathrm{O} 1}\) and \(v_{\mathrm{O} 2}\) due to the input bias currents and input offset current at \(T=25^{\circ} \mathrm{C}\).

(c) Repeat parts (a) and (b) for \(T=50^{\circ} \mathrm{C}\).
