    This brief offers a fresh insight into the behavior of PIN diodes over temperature. A simple but accurate biasing and control circuit for attenuators and other PIN diode applications is described. The circuit can easily be optimized for a high attenuation setting accuracy over a wide temperature range without using any temperature sensor or compensation circuit. View full abstract»

    The maximum data rate in today's available multidrop backplanes is significantly limited due to signal integrity concerns. In this brief, a novel gigabit multidrop serial link configuration for high-speed digital systems based on newly developed asymmetrical broadband power splitters with matching trace impedance, is presented. The proposed power splitter features good impedance match at all ports... View full abstract»

    In this brief, we present a new circuit technique to generate the sigmoid neuron activation function (NAF) and its derivative (DNAF). The circuit makes use of transistor asymmetry in cross-coupled differential pair to obtain the derivative. The asymmetry is introduced through external control signal, as and when required. This results in the efficient utilization of the hardware by realizing NAF a... View full abstract»

    The design of a finite-impulse response (FIR) filter with constraints in the frequency domain and/or time domain is considered. We further consider the design specification without explicitly specified transition band bandedges. An iterative algorithm without transition band specification is proposed to design FIR filters with various design constraints. We suggest the possible design tradeoff bet... View full abstract»

  • Nonidealities of Tow-Thomas biquads Using VOA- and CFOA-based Miller integrators

    An analysis and comparison of the performance of Tow-Thomas biquadratic filter sections, implemented with Miller integrators based on current feedback opamps (CFOAs) and voltage opamps (VOAs) was carried out. We found that the implementations with CFOAs show less parameter accuracy and an increased tendency to become unstable. Design criteria to partially overcome these drawbacks and to maximally ...

  • Output stage based high-resolution min/max and rank-order filters

    A general architecture for analog implementation of min/max, median, and other rank-order filters is presented. The circuit settles in a single iteration and exhibits low error, even for closely spaced input values or large number of inputs. Increased gain in the global feedback mechanism avoids the large corner error typical of conventional (voltage-follower based) analog winner-take-all and othe... View full abstract»

    New criteria for the uniqueness and global robust stability of the equilibrium point of the interval Hopfield-type delayed neural networks are presented. The criteria possess the structure of linear matrix inequality and, hence, are computationally efficient. View full abstract»

  • A novel CMOS operational transconductance amplifier based on a mobility compensation technique

    This brief describes a new linear operational transconductance amplifier (OTA) and its application to a ninth-order Bessel filter. To improve the linearity of the OTA, we employ a mobility compensation circuit which combines the transistors operating in the triode and the subthreshold regions. The proposed technique enhances the linearity of the transconductance without loss of the input swing ran... View full abstract»

  • Fast identification of autoregressive signals from noisy observations

    The purpose of this brief is to derive, from the previously developed least-squares (LS) based method, a faster convergent approach to identification of noisy autoregressive (AR) stochastic signals. The feature of the new algorithm is that in its bias correction procedure, it makes use of more autocovariance samples to estimate the variance of the additive corrupting noise which determines the noi...

    In this brief, several commonly used measurement configurations for common-mode rejection ratio (CMRR) are analyzed and compared with the definition; their advantages and limitations are also discussed. Finally, an improved measurement setup is proposed to characterize CMRR more accurately according to its definition over wider frequency range. View full abstract»
