Abstract :
A 3rd order active lowpass filter for antialiasing and smoothing applications, which is based on distributed RC elements, is presented together with a procedure for optimum design of this type of filter. When compared to filters using lumped resistors and capacitors, distributed filters offer steeper stopband roll-off, higher crosstalk insensitivity, and require smaller chip area.
