Operational Amplifier

An operational amplifier also called op amp is an integrated circuit or analog circuit that takes input as a differential voltage and produces output as a single-ended voltage. It is an IC that can amplify weak electric signals.An op amp has one output pin and two input pins. The basic role of an opamp is to amplify the voltage difference between the two input voltages. It is also used in filtering or to perform mathematical operations or in signal conditioning.

4. 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…
