The design and implementation of switched-current(SI) filter is proposed in this paper.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 SI second order section(biquad).Simulated results indicated a good performance of SI filter.
