A Regular Layout for Parallel Adders

TLDR
It is shown that addition of n-bit binary numbers can be performed on a chip with a regular layout in time proportional to log n and with area proportional to n.
Abstract
With VLSI architecture, the chip area and design regularity represent a better measure of cost than the conventional gate count. We show that addition of n-bit binary numbers can be performed on a chip with a regular layout in time proportional to log n and with area proportional to n.

A GHz MOS adaptive pipeline technique using MOS current-mode logic

TL;DR: An adaptive pipeline (APL) technique is described, which is a new pipeline scheme capable of compensating for device-parameter deviations and for operating-environment variations, and it is shown that MOS current-mode logic circuits are suitable for a low-noise variable delay circuit.
