Abstract
The Continuous Valued Number System (CVNS) is a novel analog digit number system which employs bit level analog residue arithmetic. The information redundancy among the digits, makes it easy to perform the required binary operations in higher radices, and reduces the implementation area and the number of required interconnections. CVNS theory can open up a new approach for performing digital arithmetic with simple and elementary analog elements, such as current comparators and current mirrors, and with arbitrary precision. In this paper we discuss the design of 16-bit radix-4 CVNS adder with controlled precision, and a two operand binary adder designed, in TSMC CMOS 0.18μm technology, is used to illustrate the techniques.
