Co-designing and cooptimizing such a quantum-classical complex system requires efficient simulators to emulate the qubits and their interaction with classical electronics. For spin-qubit readout, a single electron transistor (SET) is often employed. To build a toolset that can co-simulate the spin qubit system with the classical control and readout interface, a compact and efficient SET model is needed. This paper presents a new compact empirical SET model based on state-of-the-art SET measurement and extracted by a custom function-fitting python program. Within the target source-drain voltage range of ±1000μV , the model is accurate for circuit (SPICE) simulation. Furthermore, the empirical model is represented by a set of equations that enables instantaneous output response requiring a negligible simulation time. With this new SET model, a quantum-electronics co-simulator such as SPINE can now be enhanced to simulate the readout in addition to the control circuits of spin qubits, thus enabling the design of the complete integrated circuit (IC) required for large-scale quantum computers.","PeriodicalId":239306,"journal":{"name":"2023 19th International Conference on Synthesis, Modeling, Analysis and Simulation Methods and Applications to Circuit Design (SMACD)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128553886","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The structures are identified through stability analyses and comparisons between chain of resonators feedforward (CRFF) and chain of resonators feedback (CRFB) delta-sigma modulator (Δ∑M) configurations. Frequency tuning is predominantly achieved through altering the resonator coefficients. Therefore, the paper guides designers though the analysis process for identifying suitable tunable BP-Δ∑M structures. When moderately changing the resonators the structures perform almost identical to a non-tunable modulator optimized for the same frequency. For large frequency shifts, the out-of-band gain (OOBG) of the signal transfer function (STF) and noise transfer function (NTF) in the CRFF structure, drastically increases and the control loop becomes unstable. It is shown how utilizing CRFB structures is advantageous for frequency tuning and that the OOBG in CRFF structures can be compensated through a unity STF (USTF) Δ∑M structure.","PeriodicalId":239306,"journal":{"name":"2023 19th International Conference on Synthesis, Modeling, Analysis and Simulation Methods and Applications to Circuit Design (SMACD)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124050921","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hence, the development of a robust, industrial-level EM analysis tool is crucial. In order to address this challenge, we present PROTON, an open-source tool that can be straightforwardly integrated into industrial design flows covering a wide spectrum of EM analysis needs. On top of this, it offers an intuitive graphical user interface with a high level of automation that allows the visualization of EM stress analysis on power grid designs. The core of PROTON incorporates state-of-the-art methodologies for physics-based EM stress analysis which provide robustness and scalability in handling large-scale power grid designs. These are experimentally verified in comparison with the industrial tool COMSOL on multiple benchmarks where PROTON demonstrated a speedup of ×685 with negligible loss in accuracy.","PeriodicalId":239306,"journal":{"name":"2023 19th International Conference on Synthesis, Modeling, Analysis and Simulation Methods and Applications to Circuit Design (SMACD)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124493059","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Special logic families, such as Positive Emitter-Coupled Logic (PECL), push the technological frontier, promising even more speed at the expense of an even more strained power budget. We propose a novel hybrid of PECL and Complementary Metal-Oxide-Semiconductor (CMOS) logic to introduce Function Shut-off (FSO), realizing a shut-off at the level of functional blocks and logic primitives inside complex logic cells. Using this approach, we realize a high-speed Linear Feedback Shift Register (LFSR) in a SiGe technology, extending the State of the Art (SOTA) by adding reconfigurability, which is required for its use as sequence generator in Compressed Sensing (CS) applications. We present measurements showing successful fabrication and performance of the packaged die at 20.4 GHz. In this LFSR, employing FSO reduces the supply current by a factor of up to four (depending on the chosen configuration) and reduces active area by 17%.","PeriodicalId":239306,"journal":{"name":"2023 19th International Conference on Synthesis, Modeling, Analysis and Simulation Methods and Applications to Circuit Design (SMACD)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122869057","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
