An NMOS amplifier is to be designed to provide a 0.20-V peak output signal across a 20-kΩ load that can be used as a drain resis
tor.
(a) If a gain of at least 10V/V is needed, what gm is required?
(b) Using a dc supply of 1.8V, what values of ID and VOV would you choose?
(c) What W/L ratio is required if μnCox=200 μA/V^2? If Vt =0.4V, find VGS.

Answer:
present cost = $302218.15
Explanation:
given data
cost of the work 1st year A1 = $100,000
cost of the work 2nd year A2 = $85,000
cost of the work 3rd year A3 = $70,000
cost of the work 4th year A4 = $55,000
cost of the work 5th year A4 = $40,000
interest rate r = 6% = 0.06
to find out
present worth cost is for the first 5 years
solution
present worth cost will be here as per given equation
present cost = .........................1
here r is rate of interest and A is amount given
put here value we get
present cost =
present cost = $302218.15
