各位大侠,最近看了DAC的 Q2 random walk的布局方法,下边是我的理解:
Q2 Random Walk depends on randomizing the error so that the residual error is minimized. Hence the linear and quadratic errors are minimal, when a given current source is divided into smaller pieces and put in four quadrants. The idea of random placement is to avoid the quadratic errors.
但是,这个布局具体如何排布?是用matlab仿真出来的么?或者谁有matlab的思路,指点一下也可以。感激不尽!
