摘要

本文介绍了一种混合信号匹配滤波器的设计、实现和测试。它使用简单的电流镜来降低关键求和电路的复杂性。电路体积小,结构规则。它们可以级联成更长的过滤器。采用0.8 / SPDM数字CMOS技术,以2.5 mm/sup 2/核实现了128片测试芯片。直流和交流测试验证了设计的可行性。

Mixed signal design of cascadable matched filters
This paper presents the design, implementation, and test of a mixed signal matched filter. It uses simple current mirrors to reduce the complexity of the crucial summation circuit. The circuit is small in size and regular in structure. They can be cascaded into filters of longer length. A 128-chip test chip has been implemented in a 2.5 mm/sup 2/ core by 0.8 /spl mu/m SPDM digital CMOS technology. The DC and AC measurement assert the feasibility of the design.
