介绍了一种结构简单的新型电压型最小/最大电路。与传统的赢家通吃或基于源极跟随器的方案不同，所提出的电路的特点是所有内部节点的电压摆幅减小，并且输出阻抗非常低，这使得它们能够提供高速和高精度的操作。它们的复杂性随着输入数量的增加而线性增长。一个测试芯片原型的表征为这些特性提供了实验验证。
New voltage-mode min/max circuits are introduced that have a simple architecture. Unlike conventional winner-take-all or source follower based schemes, the proposed circuits are characterised by reduced voltage swing at all internal nodes and by a very low output impedance, which enables them to provide high-speed and high-precision operation. Their complexity grows linearly with the number of inputs. The characterisation of a test chip prototype has provided experimental verification of these features.
