A current-mode universal biquadratic filter is presented. The architecture has three input terminals, one output terminal using one differential difference current conveyor (DDCC), two grounded capacitors and two resistors. It can realize all standard second-order filter functions, which are, highpass, bandpass, lowpass, notch and allpass responses without changing the circuit topology. The pro...

Up to now we have discussed various approaches to discrete-time filter design that are all based on approximating the response of ideal lowpass, highpass, or bandpass filters, etc., with the designs involving various deterministic satisfaction of constraints such as passband and stopband ripple, and passband and stopband edge frequencies. In many actual situations we seek to design a filter tha...

Frequency ratio or frequency difference of more than fifteen times between the two bands is difficult to realize particularly for millimetre-wave applications. This paper presents a large dual band band-pass filter 5G communication and body-centric The proposed has been studied developed based on mode-composite co-planar waveguide (MC-CPW). comprises lower higher designed independently with hig...

Recently a method in FIR filter design using cosine modulation was proposed. Given a prototype M -th band lowpass filter with cutoff frequency at π M , one can obtain a new filter with comparable frequency characteristics with rational cutoff frequency. In this paper, we extend the theory to the case of arbitrary cutoff frequency. The resulting method is corresponding to finding the equivalent ...

This tutorial white-paper illustrates practical aspects of FIR filter design and fixed-point implementation along with the algorithms available in the Filter Design Toolbox and the Signal Processing Toolbox for this purpose. The emphasis is mostly on lowpass filters, but many of the results apply to other filter types as well. The tutorial focuses on practical aspects of filter design and imple...

This paper reports a multitude of HSPICE simulation results corresponding to high-order (fifth, sixth and tenth) differential classA log-domain lowpass and bandpass ladder filter topologies. The designs are elliptically approximated and were obtained by means of an appropriately extended version of the XFILTER filter compiler. The non-desirable effect of the BJT finite beta is shown; circuit mo...

Operational transconductance amplifier and capacitor (OTA-C) filters have outstood among different types of filter due to high frequency and low power capabilities in the main stream digital CMOS technology. They have been widely used in computer hard disk drive (HDD) and wireless communication transceivers. OTA-C filters based on cascade and passive ladder simulation are well-known. However, m...

The LMF60 is a high performance, precision, 6th-order Butterworth lowpass active filter. It is fabricated using National’s LMCMOS process, an improved silicon-gate CMOS process specifically designed for analog products. Switchedcapacitor techniques eliminate external component requirements and allow a clock-tunable cutoff frequency. The ratio of the clock frequency to the low-pass cutoff freque...

The integrated circuit design of a switched-capacitor filter for Bluetooth specifications is described. It was based on the optimum allocation of poles and zeros to generate a transfer function with unequal numerator and denominator orders, so that a direct-form structure with reduced number of opamps and low sensitivity to capacitor ratio errors were obtained. It was designed for implementatio...

This paper proposes a new technique for synthesis of a sharp transition, equiripple passband, low arithmetic complexity, linear phase lowpass FIR filter. The frequency response of the filter with narrow transition width is modeled using trigonometric functions of frequency and its transfer function is evolved in frequency and time domain. The synthesized filter proves to be a good alternative t...
