Continuous scaling in the technology feature size and hence the supply voltage, has directed analog designers to change the signal representation from voltage domain to current domain. That is why the high performance current-mode building blocks have received a great deal of interest. The current-mode is better than the voltage-mode in such aspects like: lower voltage supplies, lower power consumption, wider dynamic range and higher bandwidth. The current-mode circuits offer higher frequency capabilities than corresponding voltage-mode circuits due to the constant bandwidth irrespective of...

Analog designs have been viewed as a voltage dominated form of signal processing for a long time. However current-mode signal processing circuits have been preferred over the voltage-mode signal processing circuits due to their advantages such as higher signal bandwidth, larger dynamic range, greater linearity, lower power consumption, and simpler circuitry. Designs for active realizations of passive elements using high performance active devices are a rich area of research; many active elements have been used to simulate the inductor part in doubly terminated ladder filters. The researcher...

The available catalogue of active-RC circuits has evolved by accumulation of knowledge derived largely by trial-and-error. In the process of developing analog tools for circuit design automation, it is important to follow systematic methodologies to obtain novel circuits. This book presents the research work of the authors toward a generalized symbolic framework for synthesis and modeling of analog active circuits using admittance matrix representations. The proposed generalized symbolic framework allows the description of all kinds of active building-blocks along with passive elements within...
