Abstract
A method and circuit for significantly reducing the switching transients of a digital step attenuator (DSA) by employing a segmented architecture that combines thermometer and binary coded stages. This approach reduces the number of attenuator stages switching at the same time and thus minimizes any glitch amplitude. Embodiments of a segmented DSA may be realized with 'pi' and 'bridged-T' attenuators, as well as with simple tuned L-pad attenuators combined in a resistor ladder network.
