    A new approach to design the phase to sine mapper of a direct digital frequency synthesizer (DDFS) is presented. The proposed technique uses an optimized polynomial expansion of sine and cosine functions to achieve either a 60-dBc spurious free dynamic range (SFDR), with a second-order polynomial, or a 80-dBc SFDR, with third-order polynomials. Polynomial computation is done by using new canonical... View full abstract»

    The 1-bit full adder circuit is a very important component in the design of application specific integrated circuits. This paper presents a novel low-power multiplexer-based 1-bit full adder that uses 12 transistors (MBA-12T). In addition to reduced transition activity and charge recycling capability, this circuit has no direct connections to the power-supply nodes, leading to a noticeable reducti... View full abstract»

    This paper presents a new circuit technique to alleviate the uncontrollable floating-body-induced hysteretic component present in the transfer characteristics of voltage-mode CMOS Schmitt trigger circuits in a partially depleted silicon-on-insulator technology. This technique integrates a successive switching threshold shift mechanism with the systematic body contact scheme, resulting in improved ... View full abstract»

    In this study, a robust cerebellar model articulation controller (RCMAC) is designed for unknown nonlinear systems. The RCMAC is comprised of a cerebellar model articulation controller (CMAC) and a robust controller. The CMAC is utilized to approximate an ideal controller, and the weights of the CMAC are on-line tuned by the derived adaptive law based on the Lyapunov sense. The robust controller i...

    This paper considers linear repetitive processes which are a distinct class of two-dimensional linear systems of both physical and systems theoretic interest. Their essential unique feature is a series of sweeps, termed passes, through a set of dynamics defined over a finite and fixed duration known as the pass length. The result can be oscillations in the output sequence of pass profiles which in... View full abstract»

    This paper presents the first implementation of Helton's H∞ approach to wide-band impedance matching. The prototypical problem is to maximize the transducer power gain uniformly over an operating band for a load connected to a generator by a lossless two-port. The H∞ approach computes the maximum transducer power gain attainable by any lossless two-port uniformly ... View full abstract»

    A new second-generation controlled current conveyor (CCCII), implemented using a 0.8-μm Si-BiCMOS process, and operating in pseudoclass AB, is presented. It uses only n-p-n transistors to convey the signal, and CMOS transistors to bias the circuit. The expressions for the intrinsic resistance RX and class of operation are derived. The performance of the circuit in voltage and current... View full abstract»

    A simple floating current-controlled positive resistance (CCPR) circuit based upon two mixed translinear cells realized with bipolar junction transistors has been presented. The workability of the circuit and its application in realizing a variable-bandwidth bandpass filter and a new frequency shift keying generator have been confirmed by experiments and/or PSPICE simulations based upon CA3096 and...

    A new approach is presented for designing the recently introduced class of triplet halfband filterbank which are defined by three kernels. The Parametric Bernstein Polynomial is used to construct the kernels. The filterbanks have the advantage of structural perfect reconstruction and structural regularity. The design of the free parameters of the Bernstein Polynomial is achieved through a least sq... View full abstract»

    With the advent of new video standards such as MPEG-4 part-10 and H.264/H.26L, demands for advanced video coding, particularly in the area of variable block size video motion estimation (VBSME), are increasing. In this paper, we propose a new one-dimensional (1-D) very large-scale integration architecture for full-search VBSME (FSVBSME). The VBS sum of absolute differences (SAD) computation is per...
