Abstract

Adders are critical to the efficiency of arithmetic circuits in battery-powered electronic devices. This study demonstrates an 8-bit CLA (carry look-ahead adder) using single-phase ANT logic to increase the computation speed and reduce the power dissipation simultaneously. The single-phase ANT has no internal loop that optimizes the efficiency of the prior ANT. Utilizing a TSMC 40-nm technology, the proposed 8-bit CLA is fabricated. It attains the highest operating frequency of 3.2 GHz and the lowest normalized PDP (power delay product) by on-silicon measurement for 20 pF load.

使用单相全 N 晶体管逻辑的 15.13 mW 3.2 GHz 8 位进位前瞻加法器

加法器对电池供电电子设备中算术电路的效率至关重要。本研究展示了一种使用单相 ANT 逻辑的 8 位 CLA（进位前瞻加法器），可同时提高计算速度和降低功耗。单相 ANT 没有内部环路，从而优化了先前 ANT 的效率。利用台积电 40 纳米技术，制造出了拟议的 8 位 CLA。在 20 pF 负载条件下，通过硅上测量，它达到了 3.2 GHz 的最高工作频率和最低归一化 PDP（功率延迟积）。
