Hi, everybody! I have an engineering project to finish that requires me to design a MOSFET based amplifier using given specifications. Here is the project:
----------------------------
Design a single or multistage MOSFET based amplifier:
Voltage gain of at least 200. Normal or inverted output acceptable.
Small signal input resistance greater than 1 megaohm
Small signal output resistance less than 200 ohms
Allow output signal of 8 volts peak-to-peak into a load resistor of 1000 ohms
Use no more than 5 active (transistor) devices
Use standard 5% valued resistors of no more than 100K in value
Given transistor parameters:
threshold voltage = 2 V; device transconductance, K = 1 mA per volt
squared; channel modulation parameter (lambda) = 0.02 per volt.
------------------------------
I tried to first figure out how to get the output resistance, and I think it has something to do with the resistors parallel to the transistor. I know what a standard amplifier with one or two capacitors, 3 or so resistors, and one transistor looks like, but I don't know how to manipulate it to fit these specifications.
I'm really sorry for not giving more of my attempts to solve this, but I'm just so stuck. If anyone can give me any clue on how to begin, it would be greatly appreciated. Thanks!
