Active-RC Filter Design Using Impedance Tapering

Over the last few years analog signal processing has gained increasing popularity over everywhere spread digital signal processing. Especially, in the field of low power, low sensitivity and low voltage filtering applications, analog filters play an important role today. When compared to its digital counterparts, analog filters are simpler, consume less power, do not need analog-to-digital and digital-to-analog conversions, work on higher frequencies, are cheaper, etc. In this book the sensitivity problem as the main problem in the design of active-RC filters is examined, and a new and efficient design of allpole filters called impedance tapering is proposed. Besides low sensitivity, obtained filters have single amplifier and therefore consume very low power. The presented design reduces the noise, as well, which is an important performance in many modern electronic applications. The reader of this book will gain knowledge about circuit theory. The design procedure should be especially useful to professionals in Electrical Engineering and Communications Technologies fields, basically those who may be considering analog integrated-circuits and discrete-component filter design.
