Help me please... Thank you so much.
Question 7
For an op-amp amplifier circuit has a closed-loop voltagegain of 5. If the op-amp used has a gain-bandwidth productof 1.5 MHz, and we can only tolerate 10% drop in gain, whatwill be the maximum usable frequency? (help me do this question with explanation)
An op-amp with an open-loop gain of 6x105 and Vcc = 15 V has an output voltage of 3 Volts. If the inverting-input voltage is -1.8 microVolts then determine the non-inverting input voltage in microVolts to the single digit decimal place. Do not enter units. For example, if you calculate 3.1x10-6 Volts as your answer then enter 3.1. Similarly, if you calculate 1.872 x10-5 Volts as your answer then enter 18.7 (since this is 18.7 microvolts).
