Circuit modeling of multiband high-impedance surface absorbers in the microwave regime
(American Physical Society, 2011)
In this paper, we present a simple circuit model to study the absorption of electromagnetic waves by a multilayer structure with a high impedance surface in the microwave regime. The absorber consists of a stack of ...

Design methodology for FPGA implementation of lattice piecewise-affine functions
(2011)
This paper describes a design methodology to implement on FPGAs piecewise-affine (PWA) functions based on representation methods from the lattice theory. An off-line automatic processing starts at the algorithmic formulation ...

Simplified single-phase clock scheme for MOBILE networks
(Institute of Electrical and Electronics Engineers, 2011)
MOBILE networks can be operated in a gate-level pipelined fashion allowing high through-output. If MOBILE gates are directly chained, a four-phase clock scheme is required for this. A single-phase scheme is possible adding ...
