This paper proposes a new passive and exponential filter for Takagi-Sugeno fuzzy Hopfield neural networks, with time delay and external disturbance. Based on the Lyapunov-Krasovskii stability theory, Jensen’s inequality, and linear matrix inequality (LMI), a new delay-dependent criterion is proposed such that the filtering error system becomes exponentially stable and passive from the external ...

This paper presents a 600kHz MEMS bandpass filter implemented using electrical coupling of single crystal silicon HARPSS micromechanical resonators. Passive and active filter synthesis approaches based on electrical coupling of capacitive MEMS resonators are introduced and discussed. A third order passive bandpass filter at the center frequency of 600kHz with a bandwidth of 125Hz, a stopband re...

An important aspect of Software Defined Radio is the ability to define the bandwidth of the filter that selects the desired channel. This paper first explains the importance of channel filtering. Then the advantage of analog channel filtering with a variable bandwidth in a Software Defined Radio is demonstrated. This is done by comparing the requirements of the analog-to-digital converter with ...

The development of numerical techniques now permits us to analyze complex structures such as dielectric resonator filters and planar passive elements for coplanar monolithic microwave integrated circuits. In this paper, we describe a novel method for designing dielectric resonator filters. Then a Chebychev band pass filter is designed by coaxially placing high-Q TM01Q dielectric resonators ...

In this paper, a CMOS custom Integrated Circuit featuring a multi-stage Universal Switched-Capacitor (SC) Filter is Introduced. The network is based on the Generalized Immittance Converter (GIC) configuration, known for its excellent passive and active sensitivities. CMOS switches were used for elements relocation and are digitally controlled to select and realize different filter topologies. S...

This article is an excellent introduction to analog filters. It covers the basic first and second order filter types as well as the advantages and disadvantages of passive and active filters. It derives and analyzes the basic biquad implementation using several op amp implementation examples. The world of filter design is often thought of as black magic because of the myriad of configurations, ...

This paper presents a comparison between piezoelectric filtering and passive LC integrated into an HF class L?Piezo inverter. inverter is variant of ?2 where the second harmonic carried out by resonator. Piezoelectric filters are well known in signal domain (RF filtering), but their use field power electronics, as temporary energy storage element, rather recent. In piezoelectricity has mainly b...

The fundamental role of a notch filter in communication systems is the attenuation, if not outright rejection, of signals whose frequencies lie within a specified passband. If the passband identified for rejection lies at very high frequencies, passive notch filters prove more effective than their active counterparts, but their design realization is necessarily less systematic. In this paper, o...
