Single flux quantum (SFQ) technology has garnered significant attention due to its low switching power and high operational speed. Researchers have been actively pursuing more advanced devices and technologies to further reduce the reliance on inductors, bias, and dynamic power. Recently, innovative magnetic Josephson junction devices have emerged, enhancing the field of superconductor electronics (SCE) logic. This paper introduces a novel cell library design that relies entirely on Josephson junctions (JJs), showing promising potential for eliminating the need for inductors in conventional SFQ cells. This results in a 55% reduction in cell size and an 80% decrease in both static and dynamic power consumption. The proposed library implements a half flux quantum (HFQ) logic, where each pulse duration is half that of a single flux quantum pulse. The paper presents the schematics of the basic cells, emphasizing critical circuit parameters and their margins. Additionally, it examines layout blueprints, showcasing the advantageous area-saving characteristics of the proposed design.
