An op amp intended for operation with a closed-loop gain of Ω100 V/V uses resistors of 10 kΩ and 1MΩ with a bias-current-compensation resistor R3. What should the value of R3 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 voltagecan be as large as 1 mV of unknown polarity, what range of offset current is possible?
