Abstract :
An analog implementation of an order-statistics filter based on current-mode techniques is presented in this paper. The circuit is designed using switched-current delay lines and current maximum extractors. These filters could be easily incorporated to smart sensors as well as to smart cameras. SPICE simulation results demonstrate the feasibility of simple analog filters using current-mode techniques
