Abstract :
The implementation of an analog median filter with a fuzzy adaptation mechanism is discussed. The adaptive median filter is based on transconductance comparators, which saturation current is used to adapt the local weight operator. All the simulations were made using a BSIM3 Level 49 model and 1.5 μm MOSIS technology parameters.
