ABSTRACT This paper present on simple method for multiplier-free finite impulse response (FIR) filter design based on the cascade of comb and linearly tapered comb filters. The stopband frequency determines the length of the comb filter. The method is used for narrowband filters where the passband frequency is not more than 0.1 of the stopband frequency. The sharpening technique is used to sati...

Multiplication is the basic function performed in digital signal processors (DSP) and multimedia processors. Applications in DSP heavily rely on multiplication with high performance as a prime target but the major requirement is complex data handling. So, logarithmic multiplier is a practical solution for DSP functions that performs multiplication using simple addition operation. The LNS system...

Multiplier is an important circuit used in electronic industry especially in digital signal processing operations such as filtering, convolution and analysis of frequency. There are different types of algorithms used in multipliers to achieve better performance. Array multiplier and Wallace tree multiplier are such types of multipliers constructed by using CMOS logic styles such as Swing Restor...

Power, speed and area are prime design constraints for portable electronics devices and signal processing applications. Multiplier plays an important role in DSP applications. In this paper, a low power and high speed multiplier with improved column bypassing scheme is presented. Primary power reduction is obtained by disabling the supply voltage of non-functional blocks when the operands of th...

The present study evaluates four designs of XOR using our previously reported two-phase clocked adiabatic static CMOS logic (2PASCL) circuit techniques. 2PASCL XOR, which demonstrates the lowest power dissipation, is used for a 4ˆ4-bit array 2PASCL multiplier. Based on simulation results obtained using 0.18 —m standard CMOS technology, at transition frequencies of 1 to 100 MHz, the 4ˆ4-bit arra...

Some new active Voltage Controlled RC integrator and differentiator circuit realizations, with both single and differential input capabilities, using a few passive components and a current feedback amplifier (CFA) device, are proposed. A multiplier (ICL 8013) element has been appropriately utilized in the feed forward / feedback connection to obtain electronic tuning of the time constant (τo) b...

A matlab toolbox has been developed that analyzes digital lter structures. After describing the digital lter structure in a SPICE-like format, the programs of this toolbox can map a digital lter structure into a state-space description, convert a state-space description to a z-domain transfer function, compute the maximum signal magnitude when input is bounded by unity, compute noise power at t...
