    New designs of serial-parallel multipliers based on the modified Booth and multi-bit recoding algorithms are introduced. Using recoding for the parallel operand, two proposed systolic multipliers have been introduced to build structures having n/2 and n/3 cells. The proposed serial-parallel multipliers are compared with other structures on the basis of multiplication time, area, and complexity. By... View full abstract»

    As feature sizes move into the deep submicron ranges and power supply voltages are reduced, the effect of both device mismatch and inter-die process variations on the performance and reliability of analogue integrated circuits is magnified. The statistical MOS (SMOS) model accounts for both inter-die and intra-die variations. A low power analogue CMOS square-law cell, and a new transconductor and ... View full abstract»

  • Novel radix-2k square root module

    Publication Year: 2001 , Page(s): 190 - 196

    The conventional two's complement radix-2k square root algorithm requires a set of 2k full precision comparisons to generate all the 2k possible values of the partial remainder. The correct remainder is the minimum positive one of the 2k possible values. Since the number of adders of the 2k full wordlength comparisons increases exponentially w... View full abstract»

    The paper discusses and compares the application of genetic algorithm and simulated annealing methods to LC filter tuning. Specifically, the paper is concerned with the application and implementation of these methods for the development of a fast microprocessor-based automatic antenna tuning unit, providing the facility to adapt to changes in load impedance, temperature or environment. A number of... View full abstract»

    The paper deals with fault isolation in nonlinear analogue circuits with tolerance under an insufficient number of independent voltage measurements. The L1-norm optimisation problem for different scenarios of nonlinear fault diagnosis is formulated with a new fast method being presented. How to solve the L1-norm optimisation problem is discussed and a new neural network-based... View full abstract»

    A new transparent testing methodology using dynamic power supply current is proposed which is much simpler than traditional transparent testing algorithms. It employs the dynamic power supply current instead of making signatures so that it does not need the extra steps and hardware to generate a signature. The paper describes how to convert a March algorithm to a transparent one and how to cover t... View full abstract»

    In most cases, an increase in voice-coil temperature is the major cause of speaker failure. Several techniques have been developed to keep the voice coil at room temperature under high-power inputs. It is a known fact that a rise in temperature causes a rise in the total resistance of the voice coil, thus reducing the sensitivity. Many performance improvements have been implemented on sound qualit... View full abstract»

  • Theoretical study of the limitation of frequency excursion in hysteresis-mode boost-converter input stages in high power-factor AC-fed power supplies

    Switched-mode power supplies employ either variable switch duty cycle or variable switching frequency (sometimes both) associated with some feedback circuitry to deliver the required output power. Intrinsic to both techniques is the generation of electromagnetic interference (EMI) and the spectrum of this unwanted interference, conducted as well as radiated, is wide. The authors present a theoreti... View full abstract»
