The op-amps in the circuit in Figure P14.49 have an offset voltage \(V_{O S}=2 \mathrm{mV}\), an average input bias current of \(I_{B}=0.2 \mu \mathrm{A}\), and an offset current of \(I_{O S}=0.02 \mu \mathrm{A}\).

(a) For \(v_{I}=0\) and \(R_{A}=R_{B}=0\), determine the possible range in output voltages \(v_{O 1}, v_{O 2}\), and \(v_{O 3}\).

(b) Repeat part (a) for \(R_{A}=8.33 \mathrm{k} \Omega\) and \(R_{B}=10 \mathrm{k} \Omega\).
