In this paper, a new bipolar junction transistor (BJT) based configuration for providing first-order resistorless current-mode (CM) all-pass, low-pass and high-pass filter responses from the same configuration is suggested. The proposed circuit called as a first-order universal filter possesses some important advantages such as consisting of a few BJTs and a grounded capacitor, consuming very l...

A new technique for designing compact, band-pass filters of arbitrary orders is presented in this paper. The proposed approach is based on the design and optimization of a second order band-pass filter, which acts as the unit cell of a higher order filter. This unit cell is composed of slow-wave transmission line resonators, separated from one another by an inductive impedance inverter network....

C l c3 Abstract-In this paper, a design method is described for low-sensitivity narrow-band band-pass switched-capacitor filters (SCF's) using a pseudo-2-path principle and a capacitor-error-free voltage inversion. The proposed method is based on the low-pass to high-pass transformation using voltage inversion, the pseudo2-path principle, the capacitance-ratio reduction technique and a very low...

In this paper, a universal current-mode filter for simultaneously providing all the general responses such as low-pass, band-pass, high-pass, notch and all-pass responses, is proposed. The proposed biquad employs only two grounded capacitors and three identical plus-type current-controlled conveyors (CCCII+s) thus it can easily be realized in integrated circuit (IC) process. Nevertheless, it re...

We propose a two-pass median filter for impulse noise suppression in color images. The first pass is our previously presented algorithm, PNN-VMF [2]. The second pass routine is chosen dynamically on the basis of the number of pixel modifications performed by the first pass filtering. Such an approach is likely to avoid harm (e.g., blurring edges) resulting from excessive filtering. The effectiv...

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),...

A third-order Chebyshevlow-pass filter, using Gm-C structure, based on Nauta’s OTA, is presented. The filter is designed for 60GHz wireless communication using 65nm CMOS process and 1.2V power supply. The cutoff frequency of the filter is required to be tuned from 1GHz to 5GHz.UsingNauta’stransconductance characteristics, the filter can be operated at ultra-high frequency band and has a high li...
