In fact, provided the condition above holds (ie, there exists a feasible x with ¯cTx ≥ α) we can solve the problem (1) via convex optimization We make the change of variables y = x ¯cTx−α, s = 1 ¯cTx−α, so x = y/s This yields the problem minimize q yTRy subject toXfX,Y (x,y)dxdy Now suppose we have a function g(x,y) from R2 to R Then we can define a new random variable by Z = g(X,Y) In a later section we will see how to compute the density of Z from the joint density of X and Y We could then compute the mean of Z using the density of Z Just as in the discrete case there is a shortcut Theorem 1X c (y) = channel depth (varies along the length of the channel) n(x,y)= electron concentration at point (x,y) n (x,y)=the mobility of the carriers at point (x,y) Device width is Z Channel Length is L Assume a "Long Channel" device (for now do not worry about the channel length modulation effect)
