摘要

本文提出了一种新的电流划分迭代过程,并给出了实现该过程的电路。在此过程中,每次迭代包括两个阶段,每个阶段只涉及一次信号采样。通过这种方法,电流划分的准确性对器件失配不敏感。实现该过程的电路简单,每次迭代的调整步长是可变的,因此在几次迭代后可以快速达到准确的调整。此外,在该电路中,采用了一种简单有效的技术,降低了开关噪声的影响。

Device-mismatch-insensitive current divider
In this paper, a new iterative process for current division is presented and a circuit implementing the process proposed. In this process, each iteration consists of two phases and each phase involves only one signal sampling. By means of this process, the accuracy of the current division is made insensitive to the device mismatch. The circuit implementing the process is simple and the step of adjustment per iteration is variable, so that an accurate adjustment can quickly be reached after a few iterations. Also, in this circuit, the effect of the switching noise is reduced by applying a simple and effective technique.
