(a) An op-amp is connected in an inverting amplifier configuration with \(R_{2}=200 \mathrm{k} \Omega\) and \(R_{1}=20 \mathrm{k} \Omega\). The input bias current at the inverting terminal is \(1 \mu \mathrm{A}\) and the input bias current at the noninverting terminal is \(2 \mu \mathrm{A}\). Design a bias current compensated amplifier.

(b) Repeat part (a) if the input bias current at the inverting terminal is \(0.8 \mu \mathrm{A}\) and the input bias current to the noninverting terminal is \(0.5 \mu \mathrm{A}\).
