2.105 An op amp intended for operation with a closed-loop gain of –100 V/V uses resistors of 10 k and 1 M with a bias-current-compensation resistor R3. What should the value of R 3 be? With input grounded, the output offset voltage is found to be +0.30 V. Estimate the input offset current assuming zero input offset voltage. If the input offset voltage
