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…

When 10100 is input to a 5-bit digital-to-analog converter, the output current is 10 mA. What will be the output current if the input is 11101? (c) (i) (ii) Sketch the output versus input graph for a 4-bit digital-to-analog converter (DAC) which has a range from 0 V to 15 V and a resolution of 1 V. Your sketch must clearly indicate the resolution of the DAC. (iii) An analog-to-digital converter inputs a voltage ranging from 0 to 5 volts DC and converts the voltage into an 8-bit binary number. Determine the discrete steps in the output when the converter circuit resolves the input voltage from one end of its range (0 volts) to the other (5 volts)?

Q3( (A) Consider you have to analyze a Step-Down DC convertor having the following parameters: Input DC voltage - 24 V, Duty Cycle-0.65, L-20 μH, C = 15 μF, and R = 102. The switching frequency of IGBT/MOSFET Switch is 150 kHz. Analyze the above convertor for the following: a) The output voltage of the convertor b) The maximum and minimum inductor currents. c) The percent ripple in output voltage. (B) The full-bridge inverter of has a switching sequence that produces a square wave voltage across a series RL load. The switching frequency is 60 Hz, Voc-100 V, R=10. and L=25 mH. The power absorbed by load is 440 W. Analyze the above invertor for the following: (a) an expression for load current, (b) Average current in the DC source.
