Nevertheless, two floating resistors are used in the proposed GCMs. The proposed GCMs consist of three passive components. Thus, the proposed GCMs are obtained with a minimal quantity of passive components. The proposed GCMs have a high operating frequency range at a high multiplying factor. Identical passive component requirements are not needed in the proposed GCMs. In addition, the proposed GCMs can be controlled electronically by using the current-controlled current conveyor with a buffer instead of the second CFOA. However, there is no investigation on electronic tunability in this study. 0.18 μm CMOS technology parameters are employed for the CFOAs used in the proposed lossless GCMs. The layout area of the CFOA is 978.75 μm<sup>2</sup>. All simulations are performed with the SPICE program. In all simulations, supply voltages of the CFOA are selected as ±1.25 V. The simulation results verified the theoretical results from about 30 Hz to 3 MHz. The simulation results show that temperature changes do not affect the proposed GCMs much. The proposed circuits consume 1.91 mW power. In addition, the GCMs in this paper are used in the first-order active low-pass filter, and experiments of these circuits are achieved with AD844s, which are commercial devices for the CFOAs. Also, the experimental results confirm the theoretical results from about 2.5 kHz to 1 MHz.</div></div>","PeriodicalId":54973,"journal":{"name":"Integration-The Vlsi Journal","volume":"102 ","pages":"Article 102375"},"PeriodicalIF":2.2,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143146481","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing TSV-based 3D placers focus on minimizing cuts while burgeoning F2F-bonded ICs feature dense interconnection between two planar die. Towards this novel structure, we proposed an integrated adaptation methodology upon mature one-die-based placement strategies. First, we instructively utilized a one-die placer to provide a statistical looking-ahead net diagnosis. The netlist henceforth shall be coarsened topologically and geometrically using a multi-level framework. Our multi-objective gain formulation guides a level-by-level refinement of the partition. This formulation considers factors like cut expectation, heterogeneous row heights, and balanced cell distribution, enabling efficient incremental calculations at each level. Given the partition, we synchronized the behavior of analytical planar placers by balancing the density and wirelength objective function among asymmetric layers. Finally, the result will be further improved by heuristic detail placement of bonding terminals and a post-place partition adjustment. Experimental results demonstrate that our fine-grained fusion of partitioning and placement techniques are competitive compared with the top three winners of the 2022 ICCAD CAD Contest, achieving the best normalized average wirelength with competitive runtime under various 3D architectural constraints.</div></div>","PeriodicalId":54973,"journal":{"name":"Integration-The Vlsi Journal","volume":"102 ","pages":"Article 102371"},"PeriodicalIF":2.2,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143419457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
