Bit-flipping LDPC under noise conditions and its application to Physically Unclonable Functions

Alexandre Schmid, Takao Marukame

A low-density parity check (LDPC) circuit and its properties as a post-processor is proposed for physically unclonable functions (PUFs) applications. PUFs can be realized using process variations or signal noises in SRAM or other PUF circuits, whereas the ...

A Digital Spectrum Shaping Signaling Serial-Data Transceiver with Crosstalk and ISI Reduction Property in Multi-Drop Interfaces

Seyed Armin Tajalli, Yusuf Leblebici, Gain Kim, Kiarash Gharibdoust

A transceiver (TRX) architecture employing spectrum shaping signaling scheme is proposed, which can significantly reduce inter-symbol interference (ISI) and crosstalk in multi-drop interfaces. The proposed TRX architecture relies on digital implementation ...

Recent trends in low-frequency noise reduction techniques for integrated circuits

Christian Enz, Assim Boukhayma

This paper presents the two main circuit techniques, namely autozeroing (AZ) and chopper stabilization (CS), that are used to reduce the 1/f noise and offset in amplifiers typically used in sensor electronics interfaces. After recalling their main properti ...

A consensus algorithm for networks with process noise and quantization error

Colin Neil Jones, Ye Pu, Andrea Alessandretti, Francisco Fernandes Castro Rego

In this paper we address the problem of quantized consensus where process noise or external inputs corrupt the state of each agent at each iteration. We propose a quantized consensus algorithm with progressive quantization, where the quantization interval ...

Enhanced response in Brillouin distributed optical fibre sensors by simultaneous time and frequency pump multiplexing

Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Li Zhang

A technique to enhance the response of Brillouin distributed sensors is proposed and experimentally validated. The method consists in creating a multi-frequency pump pulse interacting with a multi-frequency continuous-wave probe. The power of each pulse at ...

Approximate Sparsity Pattern Recovery: Information-Theoretic Lower Bounds

Michael Christoph Gastpar

Recovery of the sparsity pattern (or support) of an unknown sparse vector from a small number of noisy linear mea- surements is an important problem in compressed sensing. In this paper, the high-dimensional setting is considered. It is shown that if the m ...
