A modified inverse-Chebyshev filter with an all positive elements ladder passive realization
نویسندگان
چکیده
This paper presents a technique to obtain a realization for passive ladder networks of the Inverse-Chebyshev lowpass filter with all positive elements. The technique consists in the shifting of transmission zeros to infinity by means of a transformation in the complex frelquency s-plane. The technique allows for multiple frequency shifts until the desired realization is obtained. Results show that there are additional improvements in group delay and in stopband attenuation.

A Novel Structure for Realization of a Pseudo Two Path Band-Pass Filter
In this paper, a modified auto zeroed integrator is used to design and simulate a low-voltage high-Q switched capacitor pseudo 2-path filter. The filter is a sixth–order Chebyshev band-pass filter operating at sampling frequency of 1MHz and center frequency of 250 kHz with a quality factor of 50. The proposed filter has both low-voltage and high speed properties of the auto zeroed integrators ...

This paper introduces four new resistorless circuits of first-order current-mode all-pass filter (CMAPF) based on dual-X current conveyor transconductance amplifier (DXCCTA). All the four circuits use a single DXCCTA and a capacitor for their realization. The main features of the proposed CMAPFs are: use of minimum active and passive components, resistorless realization, electronically adjustab...

Realization of a novel single-resistance-controlled oscillator, employing an active element and all grounded passive elements, is the purpose of this manuscript. With requirements for completing the design being only a single Voltage Differencing Current Conveyor and four grounded passive components, it is also a preferable choice for integrated circuit implementation. The designed circuit has ...
متن کاملLog-Domain Filters Based on LC Ladder Synthesis
A design method is proposed for the synthesis of linear, high-order, continuous-time filters using a unique translinear integrator circuit. Unlike previous attempts at incorporating translinear circuits into filter design, the proposed theory makes explicit use of the exponential nature of the bipolar transistor. This technique is based on the operational simulation of LC ladders. A 5th-order C...
متن کاملA Novel Multifunction CFOA-Based Inverse Filter
We present a novel multifunction inverse biquad configuration based on current feedback operational amplifiers (CFOAs) and grounded passive elements. The proposed scheme can be used to realize inverse lowpass, inverse bandpass and inverse highpass filter functions. The relevant coefficients of the inverse filters are orthogonal adjustable by independent passive elements. All the passive element...
