DESIGN AND SIMULATE A BJT AMPLIFIER USING MULTISIM AIM:Design a voltage divider BJT amplifier and then simulate using Multisim.FACILITIES REQUIRED:$1)$ MULTISIM$\mathrm{.}2)$ Computer. MULTISIM: IntroductionMULTISIM is an electronic schematic capture and simulation program which can be used to simulate analog, digital and mixed analog $/$digital circuits.MULTISIM is an open software for electronic circuit simulation with various features and is created by National Instruments $($NI$).$ It is intended for professional Engineers, educators, learners to design, investigate and check electrical circuits. MULTISIM thus merges hi$-$end SPICE simulation with a convenient graphical tool. Features of MULTISIM$1)$ User$-$Friendly InterfaceFrom the analysis of the software architecture, it can be deduced that MULTISIM is designed to have a friendly graphical user interface. Auto placement of components using the mouse pointer adds components to a circuit board, thus making it easier for a user to design a circuit$\mathrm{.}2)$ Extensive Component LibraryMULTISIM has an easily accessed and searchable repository of over $55,000$ components, which include resistors, capacitors, transistors, integrated circuits among others. Such a wide variety is beneficial to the users since it means they can procure almost any component required in their use$\mathrm{.}3)$ Advanced Simulation CapabilitiesMULTISIM employs SPICE or the Simulation Program with Integrated Circuit Emphasis as its simulation tool. On the same note, it ensures that a correct model of how the circuit behaves during transient analysis, AC and DC analysis among others is achieved. It also uses mixed mode simulation, that is$,$ both analog and digital components placed in a single mode$\mathrm{.}4)$ Virtual InstrumentsMULTISIM also has numerous virtual instruments such as oscilloscopes, multimeters and function generators and spectrum analyzers. These tools enable the users to perform experiments and evaluate their circuits with no difference to the actual conditions$\mathrm{.}5)$ Interactive Learning ToolsIn the learning area, MULTISIM has features such as simulation tools that aid the understanding of various matters by students. They include guided procedure, tests, electrostatics and current electricity visualization$\mathrm{.}6)$ Integration with LabVIEWMULTISIM can also be interfaced easily with NIs LabVIEW where users can make system designs virtually and also use HIL testing. This integration improves the ability to model, analyze, and verify the systems prior to the physical implementation$\mathrm{.}7)$ Schematic Capture and PCB LayoutLike simulation, MULTISIM has the functionalities of the schematic capture and PCB or Printed Circuit Board layout. This ensures that the users can easily move from the design aspect to the production aspect of a product. EXERCISE$1)$ Design voltage divider biased circuit to give a quiescent collector current of and a quiescent collector emitter voltage $()$ of $5$V and dc current gain of $100\mathrm{.}2)$ Add suitably sized input and output capacitors to the circuit$\mathrm{.}3)$ Amplify a small input ac signal$\mathrm{.}4)$ Use MULTISIM to simulate. Determine whether amplification has occurred and check the voltage gain and phase shift etc$\mathrm{.}5)$ Determine the impact of a varying dc current gain on the amplifier$\mathrm{.}6)$ Write a report on the work that was done. Discuss your findings and draw some relevant conclusions.
