一种高性能CMOS电流模Winner-take-all电路
High-performance CMOS current-mode Winner-take-all circuit
摘要
Abstract
A novel CMOS current-mode Winner-take-all (WTA) circuit is presented. The design utilizes a regenerative circuit to improve the resolution and speed. Without using any current mirror, a rectifier circuit is used to output the current, which improves the precision of the output current. Different from conventional WTA designs with a binary-tree structure, a new concurrent N-input WTA structure is also proposed. An 8-input WTA is implemented using TSMC 0. 18fim technology. The design is evaluated and compared with the well-known WTA benchmark circuits. Simulation results show that proposed design can provide a resolution of lnA and a precision of 99. 99%, and at the same time provide the compactness and low power. It is ideal for a variety of embedded intelligent applications.关键词
