nu MOS-based sorter for arithmetic applications
(Hindawi Publishing Corporation, 2000)
The capabilities of the conceptual link between threshold gates and sorting networks are explored by implementing some arithmetic demonstrators. In particular, both an (8×8)-multiplier and a (15,4) counter which use a ...

Efficient realization of a threshold voter for self-purging redundancy
(Springer, 2001)
The self-purging technique is not commonly used mainly due to the lack of practical implementations of its key component, the threshold voter. A very efficient implementation of this voter is presented which uses a ...
