• A Modular Programmable CMOS Analog Fuzzy Controller Chip 

      Rodríguez Vázquez, Angel; Navas González, Rafael Jesús; Delgado Restituto, Manuel; Vidal-Verdu, Fernando (IEEE Circuits and Systems Society, 1999)
      We present a highly modular fuzzy inference analog CMOS chip architecture with on-chip digital programmability. This chip consists of the interconnection of parameterized instances of two different kind of blocks, namely ...
    • A multiplexing architecture for mixed-signal CMOS fuzzy controllers 

      Vidal-Verdu, Fernando; Navas-Gonzalez, Rafael Jesus; Rodríguez Vázquez, Angel (Institution of Engineering and Technology, 1998)
      Limits to precision impose limits to the complexity of analog circuits, hence fuzzy analog controllers are usually oriented to fast low-power systems with low-medium complexity. This paper presents a strategy to preserve ...
    • Neuro-fuzzy chip to handle complex tasks with analog performance 

      Navas González, Rafael Jesús; Rodríguez Vázquez, Angel; Vidal-Verdu, Fernando (IEEE Computational Intelligence Society, 2003)
      This paper presents a mixed-signal neuro-fuzzy controller chip which, in terms of power consumption, input–output delay, and precision, performs as a fully analog implementation. However, it has much larger complexity ...
