This paper is concerned with design of cascading CIC filter and FIR filter to improve the passband droop and stopband attenuation for decimation filter. Decimation filter has wide application in both analog and digital systems for data rate conversion as well as filtering. We have three class of filters FIR, IIR and CIC filters. IIR filters are simpler in structure, but not satisfy linear phase...

A novel compact microstrip lowpass filter (LPF) is proposed in this paper, which consists of the complementary rectangle split ring defected microstrip structure (CRSR-DMS), open stubs, spurline and the dumbbell-shaped defected ground structure (DGS). Due to the unique response of the presented CRSR-DMS, a low passband insertion loss and a sharp transition of the proposed LPF was achieved. Mean...

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...

In this paper one coplanar wide band bandpass filter (BPF) is designed with end-coupled λ/4 open-stub resonator. This coplanar waveguide (CPW) BPF is designed for passband centre frequency 2.5GHz and 100% fractional bandwidth (FBW) at 3dB. The proposed structure exhibits negligible passband insertion loss, sharp transition from passband to stopband, wide attenuation bandwidth, simple fabricatio...

In this paper a novel very high performance current mirror is presented. It favorably benefits from such excellent parameters as: Ultra high output resistance (36.9GΩ), extremely low input resistance (0.0058Ω), low output (~0.18V) and low input voltage (~0.18V) operation, very low power consumption (20μW), very low offset current (1pA), ultra wide current dynamic range (150dB), and ultra high a...

In the design of IIR digital filters, the method that utilizes the classic analog filter design theory to design analog filters and then obtain the corresponding digital filters by s–z transformation is well-known. However, IIR digital filters obtained via the bilinear s–z transformation have just equal-order numerator and denominator. Having unequal-order numerator and denominator will give mo...
