Abstract
A new architecture is presented for analog median filters, without the high-accuracy reference voltage, high-speed analog summer, and linear sawtooth wave generator, thereby making it is easy to implement by VLSI technology. The features of this architecture are modular, regular, locally connected and expansible. The throughput is independent of the window size and the hardware complexity is linearly dependent on the window size
