基于模拟移位寄存器的递归滤波器设计

The Design of the Recursive Filter Based on Analog Shift Registers

BBD器件是一种MOS结构的电荷模拟移位寄存器,它可以完成对模拟信号的精确延迟。文章以BBD器件为基础,设计出了基于BBD的递归滤波器电路,并分析了原理和性能特点。

Bucket brigade device （BBD） is usually used as analogue shift register with MOS structure, which can provide an accurate delay for the analogue signal. In this paper, the recursive filter based on BBD is designed and the performance of the circuit was discussed in details.
