Design the mos amplifier above to obtain maximum gain while allowing for an output voltage swing of at least +- 0.5v. let vdd = 5v and utilize an overdrive voltage of approximately 0.2v a)specify the vds at the bias point b) what is the gain achieved? what is the signal amplitude vgs that results in the 0.5-v signal amplitude at the output? c)if the dc bias current in the drain is to be 100ua what value of rd is needed? d) if k'n = 200 ua/v^2 , what w/l ratio is required for the mosfet?
