This paper presents a single current controlled current conveyor trans-conductance amplifier (CCCCTA)based multi-input single output (MISO) voltage-mode universal biquad filter. The proposed filter employs only single CCCCTA, two capacitors and one permanently grounded resistor. The proposed filter realizes all the standard filter functions i.e. low pass (LP), band pass (BP) and high pass (HP),...

This paper presents an efficient method for the design of two-channel quadrature mirror filter (QMF) bank by polyphase representation of low-pass prototype filter and power optimization method for minimization of an objective function. The objective function is formulated as linear combination of pass-band error and stop-band residual energy of the low-pass analysis filter of the filter bank. O...

Two new current mode fully differential current conveyor (FDCCII) based multifunction filter configurations are proposed. The first proposed current mode universal filter with single input and two outputs, which can simultaneously realize current-mode low-pass (LP) and band-pass (BP), filter responses employing single FDCCII. The second proposed current mode universal filter with one input and ...

Digital Filters are generally used in the present era of communication and computation. Good performance of Digital filters is demanding one & hence it’s a challenge to design a digital finite impulse response (FIR) filter satisfying all the necessary and required conditions. Various artificially intelligent optimization techniques evolve for optimized design of digital filter. This paper demon...

A new approach to the non-expansive two band decomposition of finite length signals is introduced. The technique is based on the time-varying perfect reconstruction filter banks concept. In this approach the main analysis filter bank is instantaneously switched, at the signal boundaries, to a shorter filter bank: the D1 or Haar filter bank. The technique can be applied to all types of two band ...

A quadband filter for 1.57 GHz GPS, 5.2 GHz WLAN and 3.5 GHz Worldwide Interoperability Microwave Access is designed and tested in this work. A compact Defected Ground Structure (DGS) quad-band microstrip Band Pass Filter, stub loaded Low Pass Filter, short circuited uniform impedance resonator and ring resonator are used to maintain the size and performance. Use of stub resonator at central po...

This paper presents the design of Sharpened three stage CIC filter for decimation. The proposed decimation filter has Cascaded-Integrator Comb filter as first stage, Sharpened Cascaded-Integrator Comb filter as second and third stage. The CIC filter at first stage operates at input sampling rate, sharpened second stage operates at lower rate as compared to first stage and sharpened third stage ...

A design method for an ultra-wideband bandpass filter (BPF) with four coupled lines has been developed. For demonstration purposes, 50Ω-matched self-complementary antennas integrated with the ultra-wideband, differential-mode BPF with four coupled lines, a notch filter, and a low-pass filter (LPF) were prepared and tested. An optimized structure for a single-stage, broadside-coupled and edge-co...

This paper introduces a novel method named DEGL (Differential Evolution with global and local neighborhoods) regarding the design of two channel quadrature mirror filter with linear phase characteristics. To match the ideal system response characteristics, this improved variant of Differential Evolution technique is employed to optimize the values of the filter bank coefficients. The filter res...

Abstarct: A Band Pass Filter is one of the key components in the receive chain of any Transmit-Receive Module of an Active Array Radar. The critical parameter for the design of a BPF for a TR module is the form factor,insertion loss and rejection. Hence a microstrip based interdigital (tapped) BPF for S-Band TR Module (3.1-3.5 GHz) was designed. The filter was designed to achieve a typical inse...
