The last stage of operational Amplifier is a power amplifier. Class B is a good choice for the power amplifier. However, class B suffer from crossover distortion. Several methods are used to correct this non linearity as was discussed in the lecture (class AB). One of this method is the use of VBE multiplier. Design the output of an operational amplifier using class AB that employ VBE multiplier. For temperature stability RE can be used for the NPN and PNP...

Introduction The purpose of this project is to design, simulate, analyze, implement, and test a single-supply, multistage, transistor amplifier which fulfills a set of specifications. For this project, the pre-lab shall be treated as your formal design report and therefore must be much more detailed than usual (please see Evaluation heading on the next page of this document). The report shall be submitted to the TA by the deadline. The report is an individual assignment. Specifications • Power supply: +???...

Use IS=10-15 A, BF=100, BR=5 for all problems except for those involving a commercial part (e.g. Problem 6, 2N3904) for both hand calculation and simulation. You are asked to calculate VBE / VEB using the IS given. EB junction turn on voltage is 0.0258*In(IC/IS). So do NOT make the 0.7V assumption in design. For analysis, you can use 0.7V approximation for turn-on. 7. Build the NPN LED switch circuit below and perform the following measurements. Take photos of your circuit...

Question 8 (6 marks) You have been given a 555 Timer, an LED with Von-2V, a 9V battery that can comfortably supply 5mA of current without loss of voltage, a 1uF capacitor and access to any resistor values you want. Design a circuit that causes the LED to flash periodically once per second with a duty cycle of 75% Ensure that it does not draw more than 5mA of current from the battery (i.e 3mA of charging current and 2mA...
