    I am a student in electronics dept. in faculty of eng. in cairo univ. in the 1styear
    I am now doing the final year project , i am required to design a multistage amplifier:
    1.voltage gain>=100v/v
    4. R load=10Kohm
    5.R source=10kohm
    6.Vsource=1mv & 1KHz
    please i want any help

    First I would decide on a number of stages. If two is acceptable then that's what I would shoot for. Next we need to decide what gain to shoot for in each stage. I would pick a number a bit larger than 10 to allow for some component variation. Let's say two stages each with a gain of 12.

    So we need an amplifier stage with a gain of 12 and input impedance of 1 Mohm. What kind of transistor in what configuration will make it easy to meet those requirements. Once you have that figured out we can proceeed.
