An inverting amplifier has parameters \(R_{2}=150 \mathrm{k} \Omega\) and \(R_{1}=15 \mathrm{k} \Omega\). Bias currents of \(2 \mu \mathrm{A}\) are leaving each op-amp terminal. Determine the output voltage if the input voltage is

(a) \(v_{I}=0\),

(b) \(v_{I}=20 \mathrm{mV}\),

(c) \(v_{I}=-20 \mathrm{mV}\), and

(d) \(v_{I}=100 \mathrm{mV}\).
