A current measuring operational amplifier is made by bridging a resistor across the inverting terminal (pin 2) and the output terminal (pin 6). The noninverting terminal is grounded. a. Draw a sketch of the current measuring circuit. Determine an appropriate resistor for converting a current of 1.0 picoamperes (1.0 × 10-¹2 A) to a voltage of 0.010 V. (The math for this question is very easy, don't overthink this question. b. There are a few reasons that circuit you drew in part a will not be effective. First, you will have a difficult time finding a resistance with the required resistance value. Second, the input terminals do not have infinite resistance value. In fact, for an inexpensive 741 op-amp, the input terminal resistance may only be a few MOhms, which is far less than the resistance your calculated for the feedback resistor. This means that more current will be drawn into the op-amp than will go around it. Finally, the op-amp may have a bias current that is larger than the…arrow_forward
