摘要
本文提出了一种结构简单而精度较高的电流型排序电路.这种电路结构较为简单,其复杂度仅为 O( N ),其控制电路与偏置电路也都比较简单,它具有一定的自适应性.该排序电路主要由 W T A 网络、触发电路以及开关电流跟踪/保持电路组成.它的分辨精度取决于 W T A 电路,再现精度则主要由 P M O S电流镜和跟踪/保持电路决定.其分辨精度在 1% 之内,而其再现精度也比较高,动态范围在几微安到几百微安之间.该电路制作工艺完全与标准数字 C M O S
A novel current mode sorter circuit with compact structure and high resolution is put forward in this paper.This sorter has a simple structure with the complexity of O(N) and a large dynamic range.It also needs less clocks and biasing signals.This sorter mainly consists of WTA circuit,trigger circuit and switched current track/hold circuit.Its resolution is within the range of 1%,dependent on the resolution of WTA and switched current track/hold circuits.This circuit could be implemented in standard digital CMOS technology.
