Advances on Analog Filters for Telecommunications
2006 Advanced Signal Processing, Circuit and System Design Techniques for Communications, 2006The wireless networks popularity rapidly requires a significant effort on low-power low-cost, and highly integrated RF ICs, where the power consumption reduction of the transceiver and of each block becomes of fundamental importance. Analog base-band continuous-time filters embedded in the receiver path are here addressed with three examples. The first

This paper proposes a systematic approach for the design of a general class of analog infinite-impulse-response (IIR) filters, which includes all well-known classical analog filters as a special case. All specifications including the conventional ones and also filter flatness degrees are explicitly incorporated into design process.

Analog Complex Wavelet Filters
2005 IEEE International Symposium on Circuits and Systems, 2005This paper presents an analog implementation of the complex wavelet transform using both the complex first order system (CFOS) and the Pade approximation. The complex wavelet filter design is based on the combination of the real and the imaginary state-space descriptions that implement the respective transfer functions. In other words, a complex filter

This book chapter presents the intermediate frequency filters that are used in SSB receivers and exciters to shape the desired signal spectrum and to reduce the unwanted signals. The following topics are highlighted: passband and stopband characteristics; filter arrangements; filter types: LC filter, mechanical filter, crystal filters, and SAW filter ...

A parallel analog median filter
1998 IEEE International Conference on Electronics, Circuits and Systems. Surfing the Waves of Science and Technology (Cat. No.98EX196), 2002A continuous-time analog median filter implementation is presented. The filter uses two new circuits to implement the delay line and median blocks. Both circuits were designed a compact and modular structure to allow implementation of array processors. In addition, a novel technique for image processing is presented.

Improved Fully Differential Analog Filters
IEEE Transactions on Instrumentation and Measurement, 2007This paper proposes two novel design techniques that improve the performance of fully differential filters built by coupling two equal single-ended filters. These filters usually reach a high common-mode rejection ratio (CMRR) without using tightly matched passive components but may become unstable because of common-mode signals.

Electronic filters are used in every biomagnetic measurement, whether intentionally or not. The inherent limitations of field sensors and amplifiers impose an upper limit on the frequency of their output signal, and in some cases a lower limit as well.
