ANALOG IMPLEMENTATION OF FAST MIN MAX FILTERING/

An analog implementation of running min/max filters based on current-m ode techniques is presented in this brief, Switched-current delay cell s and current/voltage two inputs min/max selectors are used either for current or voltage inputs respectively, The voltage two input Min/Max circuit is designed using current conveyors and a modified structure of this is used to implement the running Min/Max tilter for window siz e n = 8. Simulation results demonstrate the feasibility of the propose d implementation, which can be extended to a higher window size.
