摘要
提出基于开关电流技术的滤波器设计与实现。开关电流技术是基于电流模的模拟数据采样信号处理技术,它符合集成电路的标准数字工艺,具有更高的工作频率,因而成为开关电容技术的替代技术。通过开关电流一阶节、二阶节的级联,可以实现高阶开关电流滤波器。仿真结果证实了开关电流滤波器的良好特性。
The design and implementation of switched-current （SI） filter is proposed. SI technique is a new analogue sampled-data signal processing in the current mode, which aims to replace switched-capacitors （SC） by offering superior digital process compatibility and the potential for higher operating frequencies. SI filter can be implemented by using the cascade of the first order and second order section. Simulated results indicated a good performance for SI filter.
