Conventionally, improving the SAR ADC speed compromises the signal-to-noise-and-distortion ratio (SNDR) and energy efficiency due to the high precision requirement and the sequential bit-cycling. In this design, the proposed SCS scheme reduces the parasitic capacitance in the sampling path and the settling error of the capacitive digital-to-analog converter (CDAC) with low SNDR and hardware penalties. In addition, to reduce reference ripples, active reference buffers generally consume high power while the passive methods may degrade the SNDR or occupy large areas. To efficiently reduce reference settling errors, an area-efficient SPRS is developed, which suppresses the reference settling error through the split reference segmentation. The prototype chip is fabricated in a 180-nm CMOS process and occupies an area of 0.57 mm2. Measurements show the ADC achieves a peak SNDR of 89.2 dB at 8 MS/s with a 9.5-mW power consumption.

FHSs are attached to the magnetic recording heads in modern hard disk drives (HDDs) to monitor the head-disk distance known as “fly height” by measuring the FHS resistance variation. The magnitude of the sensor signal serves as a measure of the proximity between the head and the disk surface which must accurately be controlled to minimize the fly height, thereby increasing the storage capacity of HDDs. The proposed interface includes two parts: 1) a dual-mode precise bias circuit that accurately provides a differential bias with a programmable common-mode voltage to the FHS in both voltage (V) and current (I) modes without requiring any calibrations, as well as featuring fast and smooth transient response, 2) front-end gain stages that create two separate signal paths with low- and high-frequency responses, called LF and HF blocks, utilized for controlling the fly height and mapping the roughness of the disk surface, respectively. The proposed bias circuit demonstrates high-impedance loading behavior on the sensor terminals in both V- and I- modes to have a unity signal gain at the sensor port and deliver it to the front-end amplifiers, resulting in an improvement of the overall noise performance of the interface. In addition, the bias noise power at the output of the LF block is suppressed to the extent of one order of magnitude thanks to deploying a noise cancellation technique. A low-noise and wide-bandwidth front-end is implemented for the HF block that eliminates the need for configuring the bias loop for having a low cutoff frequency, resulting in a reliable design with reduced complexity. Additionally, degenerated differential pairs with resistive loads, split tail currents, and Caprio’s quad offering low gain variation over the temperature and process are implemented as the front-end gain stages.

However, the traditional model-based fault diagnosis methods mainly focus on the rapidity and rarely consider the parameter change of bidirectional DC/DC converter, which is poor in robustness. Therefore, this paper proposes a robust open-switch fault diagnosis method for bidirectional DC/DC converters in a hybrid energy storage system (HESS) based on extended Kalman filter (EKF) with multiple corrections, where the measured currents on the battery side and the supercapacitor side are used to correct the observed currents obtained by EKF until the residuals between the observed values and the measured values are less than the set correction thresholds, thus avoiding the influence of the parameter variations. The open-switch fault detection is achieved by judging whether the correction times of the currents on the battery side and the supercapacitor side exceed the maximum correction times. The open-switch fault location is achieved through judging whether the corrected value on the fault side exceeds the set correction threshold. The proposed method is validated through simulation and experimental studies. Both the results show the robustness of fault diagnosis for bidirectional DC/DC converter.","PeriodicalId":13039,"journal":{"name":"IEEE Transactions on Circuits and Systems I: Regular Papers","volume":null,"pages":null},"PeriodicalIF":5.2,"publicationDate":"2024-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142090826","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Initially, within the framework of optimal control theory, we employ the reinforcement learning (RL) algorithm to derive an approximate solution to the Hamilton-Jacobi-Bellman equation (HJBE). Specifically, the neural networks (NNs) are utilized to construct the Actor-Critic structure with the aim of implementing control behavior and evaluating system performance, respectively. An additional network is employed to address nonlinear uncertainties existing in the system. Furthermore, we design a static threshold event-triggered mechanism (ETM) to achieve the event-triggered state feedback-based control strategy. By utilizing this event-triggered state information, we reconstruct the approximate optimal controller and update laws of neural network weights, effectively reducing the communication burden while ensuring that all signals of the MASs remain bounded. Finally, two simulation examples are carried out to demonstrate the feasibility of the proposed method.","PeriodicalId":13039,"journal":{"name":"IEEE Transactions on Circuits and Systems I: Regular Papers","volume":null,"pages":null},"PeriodicalIF":5.2,"publicationDate":"2024-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142090705","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The forward error correction (FEC) codes specified in this standard include low-density parity-check convolutional codes (LDPC-CCs), Reed-Solomon (RS) codes, and RS convolutional concatenated (RSCC) codes. This work proposes a low-complexity decoder fully compliant with the standard. First, a heterogeneous scheme is introduced to LDPC-CC decoding. The new scheme assigns different data formats among processing elements (PEs), which reduces the overall storage size and enables a customized datapath down to the PE level. Then, to efficiently support diverse FEC demands in the standard, a reconfigurable architecture is thoroughly explored from both memory and datapath aspects. Leveraging these techniques, the first decoder compatible with the IEEE 1901 standard is developed and implemented with 55nm technology. Implementation results demonstrate that the proposed decoder satisfies the standard’s requirements while exhibiting low hardware complexity.","PeriodicalId":13039,"journal":{"name":"IEEE Transactions on Circuits and Systems I: Regular Papers","volume":null,"pages":null},"PeriodicalIF":5.2,"publicationDate":"2024-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142368489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
