Abstract: This work contains a brief study of a new structure of a low-pass filter of N th order, operating in low frequencies. The low-pass filter is designed with CMOS technology and biased to work in weak inversion. The dimension of the lay-out of the circuit and very low power consumption enables this new structure be integrated in a single chip. The parameter n, dependent of the fabricatio...

This paper describes a low-voltage and low-power Gm-C low pass filter. The low-pass filter that precedes the A/D converter is called anti-aliasing filter. In the analog signal processing, the anti-aliasing filter would be one of the most important circuits in the transceiver architecture. This filter is located in the analog front-end circuits of DAB receivers. The 4 – order butterworth Gm-C lo...

Complementary infinite-impulse response (IIR) filter pairs can be synthesized to generate power-complementary, allpass complementary, or magnitude-complementary filter pairs (see, e.g., [1]). A very attractive alternative to generate a power-complementary low-pass/high-pass IIR filter pair is to use lattice wave digital (LWD) filters (parallel connections of two all-pass filters) [2]–[4]. Usual...

This paper aims to reveal the relationship between the minimum L2-sensitivity of state-space digital filters and the Gramian-preserving frequency transformation. To this end, we first give a prototype low-pass state-space filter in such a manner that its structure becomes the minimum L2-sensitivity structure. Then we apply the Gramian-preserving (LP-LP) frequency transformation with a tunable p...

An eigenvalue-eigenvector approach for the design of two-channel linear phase quadrature mirror filter (QMF) bank is proposed. To reduce the computational complexity, finite-duration impulse response (FIR) low-pass prototype filter of the filter bank is represented by polyphase components. The design problem is formulated to optimize the filter tap weights of the low-pass prototype filter of th...

This project is intended to build a microstrip low pass filter with a pass band till 3 GHz at 3 dB cutoff frequency. This project is divided into two stages. In the first stage, a conventional seven pole low pass filter using commensurate length 8 / g λ is designed by converting the value of g1 to g7 into unit elements as well as open circuit stubs. In second stage, a method to design low pass ...
