In this paper a new CMOS realization of ZC-CG-CDBA (Z Copy-Controlled Gain-Current Differencing Buffered Amplifier), a recently published active element, is proposed. In addition, the performance of the circuit designed is demonstrated on a second order single input-three output filter example employing two ZC-CG-CDBA elements. The natural frequency and the quality factor of the filter are adjustable...
A configuration for the realization of voltage mode second-order filters employing a single second generation inverting current conveyor as the active element is presented. This topology can synthesize lowpass, highpass, bandpass, notch and allpass filtering functions. Theoretical analysis is verified with SPICE simulation results.
In this paper, an iris recognition system based on fast iris localization and phase correlation matching is proposed. Eye images are captured from a CMOS image sensor on infrared (IR) illumination condition using a digital signal processor (DSP) kit. Afterwards, fast iris localization and normalization are performed on DSP, and normalized iris images are sent to the server via ethernet interface and...
Memristor is a passive two terminal electronic device that maintains a functional relationship between the time integrals of current and voltage. Memristor theory was proposed and described by Leon Chua in 1971. But the first practical implementation has been realized by Williams' group at HP laboratory in 2008. Memristor has drawn the worldwide attention after HP released its invention. This paper...
Last decade witnessed the rapid development of Wireless Sensor Networks (WSNs). More recently, the availability of inexpensive hardware such as CMOS cameras and microphones that are able to ubiquitously capture multimedia content from the environment has fostered the development of Wireless Multimedia Sensor Networks (WMSNs). Nodes in such networks require significant amount of processing power to...
In this study, a rule based perceptual intonation model was proposed for Turkish text-to-speech synthesis systems. A proper intonation model is required for a natural synthesized speech. The proposed model is sentence based and includes the stress patterns of compounds, inflected verbs and some punctuation marks. The offered rules were determined with the help of an interface where acoustical properties...
