Abstract

This paper proposes two bounded arithmetic operations, which are easily realized with current signals. Based on these two operations, a bounded algebra system suitable for describing current-mode digital circuits is developed and its relationship with the Boolean algebra, which is suitable for representing voltagemode digital circuits, is investigated. Design procedure for current-mode circuits using the proposed algebra system is demonstrated on a number of common circuit elements which are used to realizd arithmetic operations, such as adders and multipliers.
