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 ...

Reliable analysis of settling errors in SC integrators - application to high-speed low-power ΣΔ modulators design
(1999)
This paper presents a detailed study on the transient response of SC integrators taking into account the effects of amplifier finite gain-bandwidth product and slew-rate during, unlike previous models, both the integration ...

Multiplexing architecture for mixed-signal CMOS fuzzy controllers
(Institute of Electrical and Electronics Engineers, 1998)
Limited precision imposes limits on the complexity of analogue circuits, and hence fuzzy analogue controllers are usually oriented to fast low-power systems with low-medium complexity. A strategy to preserve most of the ...
