please immediately, have no time. I wanna check my details actually. I need in an hour.. the last number if my ID is 4. goal of the project introduction theoretical work analysis conclusion are the most important parts of the homework.

Design Question: Design an amplifier circuit that has an input signal Va*sin(2*2*5KHz*t). At the input stage, the circuit compares the input voltage peak value to 3.3VDC. If the input signal peak value greater than 3.3VDC, the circuit amplifies the signal depending on your student ID (the last digit of your student ID will be taken. (e.g. When your student ID is 20110701026, the circuit MUST amplify the signal 6 times (6*Va* sin(2*r*5KHz*t)). If the last digit of your number is 0, it means amplifier gain is 10). Otherwise, the output of the circuit is 0. For the design, you are only allowed to use positive DC source. It means that you cannot use the DC source as a negative source by connecting reversely to the ground. However, at the end of the circuit, there should only be AC voltage without any distortion. You must use at least 1 Op-amp, 1 Zener Diode in your design In your report, you need to inform about your circuit stage by stage (if you make any calculations, please show them). The report must contain the circuit schematic(s) and the output graphs for Va>3.3V and Va
