An op amp is connected in a closed loop with gain of +100 utilizing a feedback resistor

Chapter 2, Problem 2.104

(choose chapter or problem)

An op amp is connected in a closed loop with gain of +100 utilizing a feedback resistor of 1 M. (a) If the input bias current is 200 nA, what output voltage results with the input grounded? (b) If the input offset voltage is 2 mV and the input bias current as in (a), what is the largest possible output that can be observed with the input grounded? (c) If bias-current compensation is used, what is the value of the required resistor? If the offset current is no more than one-tenth the bias current, what is the resulting output offset voltage (due to offset current alone)? (d) With bias-current compensation as in (c) in place, what is the largest dc voltage at the output due to the combined effect of offset voltage and offset current?
