Aggressive Area Scaling in Passive Transresistance Networks

the issue of very aggressive area scaling to practically achieve large transresistance in a small amount of area is addressed. Closed form analytical expressions for the area scaling efficiency for an R-2R transresistance network and a ladder-based transresistance network are presented. Closed form analytical expressions and numerical comparisons for the standard deviation of the transresistance of these networks that are useful for determining ratio matching yield are also included.
