PART I – Linear Series Regulator Simulation Schematic   Observation DC Sweep: Calculation Let us calculate the Output voltage theoretically. Therefore,           V (Zener) = 4.7 V; (Taken from the Datasheet) and R 2 = R 3 = 1kΩ; Operation of the circuit                                        Circuit shown in the figure which we built is an ‘Op-Amp Shunt Regulator’. Same like in Series Regulator, the Op-Amp is connected here as a Comparator which compares the samples output and the reference Voltage taken from the Zener Diode. In contrast, the Control element ‘the transistor’ is connected in parallel here. So in here as the Output voltage increases, the comparator detects it via the feedback loop by comparing it to the reference voltage. As the feedback loop is connected to the positive terminal of the Op-Amp, the comparator detects a higher difference between the inputs incase of higher output Voltage. Due to this the Op-Amp output is increased which drives the transisto
