      A 151 dB high dynamic range CMOS image sensor chip architecture with tone mapping compression embedded in-pixel  [Article]

      Vargas Sierra, Sonia; Liñán Cembrano, Gustavo; Rodríguez Vázquez, Ángel Benito (Institute of Electrical and Electronics Engineers, 2015)
      This paper presents a high dynamic range CMOS image sensor that implements an in-pixel content-aware adaptive global tone mapping algorithm during image capture operation. The histogram of the previous frame of an auxiliary ...

      All-MOS implementation of RC networks for time-controlled Gaussian spatial filtering  [Article]

      Fernández Berni, Jorge; Carmona Galán, Ricardo (Wiley-Blackwell, 2012)
      This paper addresses the design and VLSI implementation of MOS-based RC networks capable of performing time-controlled Gaussian filtering. In these networks, all the resistors are substituted one by one by a single MOS ...

      Autoregressive time series prediction by means of fuzzy inference systems using nonparametric residual variance estimation  [Article]

      Montesino Pouzols, Federico; Lendasse, Amaury; Barriga Barros, Ángel (Elsevier, 2010)
      We propose an automatic methodology framework for short- and long-term prediction of time series by means of fuzzy inference systems. In this methodology, fuzzy techniques and statistical techniques for nonparametric ...

      Context-dependent transformation of Pareto-optimal performance fronts of operational amplifiers  [Article]

      Roca Moreno, Elisenda; Velasco Jiménez, Manuel; Castro López, Rafael; Fernández Fernández, Francisco Vidal (Springer, 2012)
      The use of Pareto-optimal performance fronts in emerging design methodologies for analog integrated circuits is a keystone to overcome the limitations of traditional design methodologies. However, most techniques to generate ...

      Does the use of nest materials in a ground-nesting bird result from a compromise between the risk of egg overheating and camouflage?  [Article]

      Gómez, Jesús; Liñán Cembrano, Gustavo; Ramo, Cristina; Castro, Macarena; Pérez Hurtado, Alejandro; Amat, Juan A. (Company of Biologists, 2019)
      Many studies addressing the use of nest materials by animals have focused on only one factor to explain its function. However, the consideration of more than one factor could explain the apparently maladaptive choice of ...

      Domino inspired MOBILE networks  [Article]

      Nuñez Martínez, Juan; Avedillo de Juan, María José; Quintana Toledo, José María (Institute of Electrical and Electronics Engineers, 2012)
      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. A single phase scheme has been recently reported ...

      Mixed-mode impedance and reflection coefficient of two-port devices  [Article]

      Carrasco, T.; Sieiro, J.; Lopez-Villegas, J. M.; Vidal, N.; González Echevarría, Reinier; Roca Moreno, Elisenda (EMW Publishing, 2012)
      From the point of view of mixed-mode scattering parameters, Smm, a two-port device can be excited using different driving conditions. Each condition leads to a particular set of input reflection and input impedance coefficient ...
