The area of the digital controller is 62% smaller compared to the sum of the digital controller area of four independent LDOs. An analog-assisted loop and a push-pull auxiliary loop are used to take over the control in steady state to save quiescent power, reduce output ripple and enhance the response speed.

An undershoot voltage of 100mV is measured with a 47mA/20ns load step, resulting a figure-of-merit as low as 0.12ps.","PeriodicalId":402948,"journal":{"name":"ESSCIRC 2019 - IEEE 45th European Solid State Circuits Conference (ESSCIRC)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125609144","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}

Both architecture-level and circuit-level optimizations are presented. From the perspective of processor architecture, the PTLL-BNN includes two new design choices. First, the proposed BNN accelerator is placed close to the SRAM of the embedded processors (i.e., physically tightly coupled and near-memory); thus, the extra SRAM cost that is incurred by the accelerator is as low as 0.5 KB. Second, the accelerator is a memory-mapped IO (MMIO) device (i.e., logically loosely coupled), so all embedded processors can be equipped with the proposed accelerator without the burden of changing their compilers and pipelines. From the circuit perspective, this work employs four techniques to optimize the power and costs of the accelerator. First, this design adopts a unified input-kernel-output memory instead of separate ones, which many previous works adopt. Second, the data layout that this work chooses increases the sequentiality of the SRAM accesses and reduces the buffer size of storing the intermediate values. Third, this work innovatively proposes to fuse the max-pooling, batch-normalization, and binarization layers of the BNNs to significantly reduce the hardware complexity. Finally, a novel methodology of generating the scheduler hardware of the accelerator is included. We fabricate the accelerator using the TSMC 180 nm technology. The chip measurement results reach 91 GOP/s on average (307 GOP/s at peak) at 200 MHz. The achieved GOP/s per million logic gates and GOP/s per KB SRAM are 2.6 to 237 times greater than that of previous works, respectively. We also realize an FPGA system to demonstrate the recognition of CIFAR-10/100 images using the fabricated accelerator.","PeriodicalId":402948,"journal":{"name":"ESSCIRC 2019 - IEEE 45th European Solid State Circuits Conference (ESSCIRC)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115235329","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}

Unfortunately, due to transmission line (TL) dispersion, RTWOs suffer from flicker noise upconversion. In this letter, we propose a \"distributed stubs\" technique to mitigate this mechanism. To cancel out phase shifts due to the TL dispersion, we intentionally generate a phase difference between TL modes. The proposed 26.2–30 GHz RTWO is implemented in 22-nm FD-SOI CMOS. At 30 GHz, it achieves PN of − 107 and −128.1 dBc/Hz at 1 and MHz 10 offsets, respectively. This translates into figure-of-merits (FoM) of 183.5 and 184.6 dBc/Hz, respectively.

It achieves a flicker noise corner of 100 kHz, which is an order-of-magnitude better than currently achievable by state-of-the-art mmW RTWOs.","PeriodicalId":402948,"journal":{"name":"ESSCIRC 2019 - IEEE 45th European Solid State Circuits Conference (ESSCIRC)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115340248","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}
