The Current State of Circuit Lower
1. Abstract We review the existing results showing languages to be outside of complexity classes deened by tight constraints on boolean circuits, using the new characterizations of these classes in terms of automata theory BT88] and formal logic BIS88]. We outline the methods and results in the case of three types of classes deened by circuits of constant depth, polynomial size, and unbounded f...
متن کاملCurrent-mode Multiple-input Max Circuit
A CMOS continuous time current-mode circuit which provides the maximum of n analog inputs is presented. This structure exhibits a O(n) complexity, and allows high precision and speed with small area and very low power dissipation. Its operation is discussed and illustrated with simulation results. INTRODUCTION Multiple-input Max/Min circuits are basic building blocks in many advanced computatio...
متن کاملCurrent-mode square rooting circuit using CCCDTA
In this paper, a novel circuit realizing the square rooting function in current-mode is presented. The circuit makes use of a recently proposed active building block (ABB), namely the current controlled current differencing transconductance amplifier (CCCDTA). The circuit offers the following advantages: (i) a complete current-mode circuit makes it suitable for current-mode signal processing ap...

متن کاملA Cmos Current-mode Multiplier/divider Circuit
Combination of A/D-D/A converters allows implementing multiplier/divider operations. An efficient design based on continuous-time, current-mode, dividing-algorithmic converters is presented in this paper. It offers high speed and capability of low voltage operation, and it is suitable for applications of low or middle resolution (below 9 bits). In addition, the division result is given in both ...
