An op-amp intended for operation with a closed-loop gain of -100 V/V uses resistors of 10 kN and 1 Mn with a bias-current-compensation resistor R3. Assuming an ideal voltage source at the input, what should the value of R3 be? With input grounded, for one particular op-amp, the output offset voltage is found to be +0.30 V. Estimate the input offset current assuming zero input offset voltage. In this case, if we know the input offset current is one-tenth the bias current what value of R3 will result in zero output offset voltage?

Question
Transcribed Image Text:An op-amp intended for operation with a closed-loop gain of -100 V/V uses resistors of 10 k2 and 1
MQ with a bias-current-compensation resistor R3. Assuming an ideal voltage source at the input,
what should the value of R3 be? With input grounded, for one particular op-amp, the output offset
voltage is found to be +0.30 V. Estimate the input offset current assuming zero input offset voltage.
In this case, if we know the input offset current is one-tenth the bias current what value of R3 will
result in zero output offset voltage?
