Using a modified multiline method, we have extracted the propagation constants with uncertainty propagation analysis. This considered instrumentation noise, length uncertainty, and impedance mismatch caused by variations in cross-section due to the fabrication capabilities of each manufacturing process. By reformulating the propagation constant, we obtained the attenuation per unit length and the effective relative permittivity as a function of frequencies up to 43.5GHz with 95% confidence interval. These results showed good agreement with full-wave simulations and highlighted the differences between the PCB manufacturing processes.","PeriodicalId":50387,"journal":{"name":"Ieice Electronics Express","volume":"74 23","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135088356","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, existing hardware solutions cannot provide efficient event-based DNN accelerations owing to the characteristic of event streams, which are typically in low datarate and high-dynamic range. In this letter, we present a novel hardware design that can handle event-based DNNs according to the data characteristic of event streams. Furthermore, we provide a dataflow that enables flexible DNN data encodings (including both bitmask and compressed sparse row (CSR)) based on the event data characteristic for energy saving. Comprehensive evaluations based on four famous event-based benchmarks show that the proposed design can achieve higher performance and better energy efficiency compared with representative accelerator baselines.","PeriodicalId":50387,"journal":{"name":"Ieice Electronics Express","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135088526","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To avoid the bulky off-chip image-rejection filter, the Hartley transmitter structure is employed, in which frequency plan is undertaken to improve the IRR and LOFT performance, and a two-stage polyphase filter (PPF) and an in/quadrature-phase (I/Q) Gilbert mixer are utilized to improve the IRR further. With the capacitive neutralization and transformer-based series power combining techniques, a two-stage power amplifier (PA) is used to obtain high gain and output power. In the LO buffer, a flexible phase inverting cascode structure is used to achieve reliable up-sideband operation, and the inductive peaking technique and cross-coupled transistor pair are employed to promote the LO swing. Fabricated in a 65-nm CMOS process, the proposed Ku-band transmitter occupies a chip area of 0.98 mm2, and consumes 304-mW power consumption from a 1.2-V supply voltage. With measurements, over 15.8-17.9-GHz radio frequency (RF) bandwidth, the transmitter achieves an IRR and LOFT suppression ratio of 45-55 and 43-52 dBc, respectively. Moreover, it exhibits a conversion gain of 28.5 dB, an output 1-dB compression point (OP1dB) of 13.3 dBm and a saturated output power (Psat) of 16 dBm.","PeriodicalId":50387,"journal":{"name":"Ieice Electronics Express","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135492966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
