In the last two decades, current-mode (CM) circuits have received more attention. These types of circuits offer many advantages such as wider bandwidth, bigger dynamic range, better linearity and more IC suitability when compared with voltage mode (VM) topologies [1, 2]. In addition to this, electronic tunability is also one of the other important issues in electronic design since it allows us ...

Chemotaxis is defined as a behavior involving organisms sensing attractants or repellents and leading towards or away from them. Therefore, it is possible to reengineer chemotaxis network to control the movement of bacteria to our advantage. Understanding the design principles of chemotaxis pathway is a prerequisite and an important topic in synthetic biology. Here, we provide guidelines for ch...

Background Traditional muscle fatigue indices (Fmean and Fmed) have a relatively low sensitivity under dynamic exercise conditions. Various muscle fatigue indices have been attempted to overcome this problem [1,2]. However, their methods required large amounts of computation and had limitations in time-frequency resolution [3]. Kim et al. introduced the use of a filter-based fatigue index (FIhl...

The objective of this study is to inkjet print resistor-capacitor (RC) low pass electrical filters, using a novel water-based cellulose graphene ink, and compare the voltage-frequency and transient behavior to equivalent circuits constructed from discrete passive components. The synthesized non-toxic graphene-carboxymethyl cellulose (G-CMC) ink is deposited on mechanically flexible polyimide su...

Transfer entropy (TE) provides a generalized and model-free framework to study Wiener-Granger causality between brain regions. Because of its nonparametric character, TE can infer directed information flow also from nonlinear systems. Despite its increasing number of applications in neuroscience, not much is known regarding the influence of common electrophysiological preprocessing on its estim...

In this paper we present a simplified analog VLSI inner hair cell model, which models the main characteristics of the biological inner hair cell, i.e., I ) soil half-wave rectification, 2 ) low-pass filtering at IkHz, and 3) adaptation to sustained input. The main challenge lies in the creation of the long time constant associated with the lkHz low-pass filter and the adaptation. A modified cur...

Multi-image interpolation in space and time has recently received considerable attention. Typically, the interpolated image is synthesized by adaptively blending several forward-warped images. Blending itself is a low-pass filtering operation: the interpolated images are prone to blurring, even if correspondences are perfect. Furthermore, ghosting artifacts appear as soon as the underlying corr...

In this paper an analysis of the classical highorder Extremum Seeking Control (ESC) scheme is presented in comparison with an improved ESC variant proposed here. The proposed ESC scheme is based on a band-pass filter instead of the series combination of highpass and low-pass filters used in the classical ESC scheme. The relation between the search speed and the derivatives of the unknown input-...

A 4 th order Gm-C elliptic low-pass filter with a wide continuous tuning range is presented. The continuous tuning is achieved by means of a new tuning circuit which adjusts the bias current of the Gm cell’s input stage to control the cut-off frequency. With this tuning circuit, power efficiency is achieved by scaling down the power consumption proportionally to the cut-off frequency while keep...

This paper presents effectiveness of cut off frequency of a low pass filter of communication disturbance observer (CDOB). This compensation technique requires system model only and not time model. So we can apply this compensation technique to both constant and variable time delay. In this paper, the validity of compensation technique with simulated result has been shown.
