D*2.99 A noninverting amplifier with a gain of +10 V/V using 100 kΩ as the feedback resistor operates from a 5- kΩ source. For an amplifier offset voltage of 0 mV, but with a bias current of 2 µA and an offset current of 0.2 µA, what range of outputs would you expect? Indicate where you would add an additional resistor to compensate for the bias currents. What does the range of possible outputs then become? A designer wishes to use this amplifier with a 15- kΩ source. In order to compensate for the bias current in this case, what resistor would you use? And where?
