Abstract :
A continuous-time analog median filter implementation is presented. The filter uses two new circuits to implement the delay line and median blocks. Both circuits were designed a compact and modular structure to allow implementation of array processors. In addition, a novel technique for image processing is presented. The circuit was designed for a 2 μm technology MOSIS process
