For the circuit in Figure P14.49, the op-amps are ideal except that the opamps have bias currents of \(I_{B}=3 \mu \mathrm{A}\) entering each op-amp terminal.

(a) For \(v_{I}=0\) and \(R_{A}=R_{B}=0\), determine the values of \(v_{O 1}, v_{O 2}\), and \(v_{O 3}\).

(b) Determine the values of \(R_{A}\) and \(R_{B}\) for input bias current compensation.

(c) If the average input bias current is \(I_{B}=3 \mu \mathrm{A}\) and the input offset current is \(I_{O S}=0.3 \mu \mathrm{A}\), determine the worst-case output values of \(v_{O 1}\), \(v_{O 2}\), and \(v_{O 3}\) using the results of part (b).
