Hi all professionals engineers
I'm new member in this forum and I having a problem on understand the cascading amplifier. My coursework is request me to amplify a 10mV input with audio frequency to 2V peak-to-peak output that driving 10kohm resistive load. In this design, we require to build the buffer stage, gain stage and an output stage to drive the output loading.
I did a circuit with calculation that based on my knowledge that learn in the class but I keep getting the results that no amplifying the input but decade the input voltage to nano voltage :X
So the problem I want to know is:
1. What is buffer stage, gain stage and output stage is really doing?
2. Any more idea to improve my circuit on the attachment? Give me some advice.
3. I using UCE x2 and EFCx1 in this circuit. UCE is the gain stage I think to amplify the signal input and EFC is output stage to show the output.
Thank you for the expert help
Your help is appreciate
