A HIGH-SPEED MEDIAN CIRCUIT

A high-speed analog median circuit is presented using a two-stage arch itecture to minimize the errors around the transition corners, Prototy pes have been designed and built using the Orbit 2-mu m CMOS process, The design has been optimized for low crossover distortion and fast tr ansient recovery in less than 200 ns, The active area is 0.2 mm(2), an d the circuit dissipates 7 mW from a single 5 V supply while being abl e to drive an external 30 pF capacitor.
