One of the most important tasks in design and manufacturing of integrated circuits is the testing phase. Distinguishing between faulty and fault free ICs is a difficult task Therefore, simulations are being done for different circuits to identify fault free and faulty circuits. The circuits include analog circuits, digital circuits &mixed signal circuits. Analog circuits like Low pass filter, H...

This paper reports a novel band pass filter without any periodic response. The novel filter has been named Rectangular Parallel Coupled Line filter (RPCL) and derived from reforming the conventional parallel coupled line filters. The novel band-pass filter has narrowband response. RPCL filter with center frequency of 475 MHz, 1 dB pass-band of 10MHz and 25 dB stop-band of 50MHz has been reporte...

Median filter is quite effective in recovering the images confounded by salt and pepper noise. It discards outliers (impulses) effectively, but it fails to provide adequate smoothing for images corrupted with non-impulse noise. In this paper, two nonlinear techniques for image filtering, namely, New Filter I and New Filter II are proposed based on a nonlinear high-pass filter algorithm. New Fil...

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...

This paper develops a design of two-dimensional (2D) digital filter with monotonic amplitude-frequency responses using Darlington-type gyrator networks by the application of Generalized Bilinear Transformation (GBT). The proposed design provides the stable monotonic amplitude-frequency responses and the desired cutoff frequency of the 2D digital filters. This 2D recursive digital filter design ...

This paper presents two novel electronically tunable universal filter configurations employing a single new active device, namely the current follower transconductance amplifier (CFTA). The first proposed current-mode universal filter with single input and three outputs consists of one CFTA, one virtually grounded resistor and two grounded capacitors. It can simultaneously realize low-pass, ban...

Traditional continuous-time filters are of integer order. However, using fractional calculus, filters may also be represented by the more general fractional-order differential equations in which case integer-order filters are only a tight subset of fractional-order filters. In this work, we show that low-pass, high-pass, band-pass, and all-pass filters can be realized with circuits incorporatin...

The `ideal' band pass ̄lter can be used to isolate the component of a time series that lies within a particular band of frequencies. However, applying this ̄lter requires a dataset of in ̄nite length. In practice, some sort of approximation is needed. Using projections, we derive approximations that are optimal when the time series representations underlying the raw data have a unit root, or are...

This paper presents a new second order multifunction filter using one active element, requiring only ‘twelve’ CMOS transistors, and four passive elements. The proposed circuit realizes voltage-mode low-pass, high-pass and band-pass functions with the advantages of minimum component count structure, high Q possibility, and high frequency potential. The proposed circuit is verified through PSPICE...
