Currently the range of SHF systems using modulated backscattering at passive transponders is limited by this effect. To overcome this problem we propose a new array structure connecting multiple antennas and rectifiers through a passive network. By using the proposed approach on an ${N}times{N}$ array, energy and backscatter range can both be increased by a factor of N. This enables radio frequency identification (RFID) systems in the SHF band to achieve similar coverage as ultra high frequency (UHF)-RFID systems, while gaining the advantage of higher available bandwidth. Influences from the direct environment of the transponders can be compensated for and the possibility of high accuracy transponder localization arises.","PeriodicalId":142196,"journal":{"name":"2022 17th Conference on Ph.D Research in Microelectronics and Electronics (PRIME)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130548847","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 first technique, known as photon coincidence technique, exploits the temporal proximity of multiple detections to reject background light and maximize the detection of photons belonging to the target reflection. The second technique, named Auto-Sensitivity (AS) technique, reduces the photon-detection probability (PDP) if a certain background illumination level is detected, to avoid the risk of saturating SPADs due to intense background level. The two methods are first compared to each other, showing that the photon coincidence technique outperforms the AS technique. Then, the two techniques are operated together, resulting in an increase of the maximum achievable measurement range if the AS technique is applied on top of the photon coincidence technique.","PeriodicalId":142196,"journal":{"name":"2022 17th Conference on Ph.D Research in Microelectronics and Electronics (PRIME)","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133947345","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 original aspect of the proposed solution is the ability to generate linearly interpolated signals by means of analog interpolation.

The potentiality of the proposed approach was verified by means of electrical simulations performed on a prototype designed with a standard $0.18mu{mathrm m}$ CMOS process. A THD as low as 0.59%, calculated considering also the aliasing effect implied by the linear interpolation, was obtained at a 100 kHz sinewave frequency. The power consumption is around 300 $mu{mathrm W}$. The possibility of varying the sinewave frequency in a 3-decade wide range was also assessed.

Mitigating Cache Contention-Based Attacks by Logical Associativity 通过逻辑关联减轻基于缓存争用的攻击

One of the most well-known implementations, CEASER-S, applies an encryption cypher with a periodically changing key as a cache indexing function. By increasing the re-keying frequency, CEASER-S can defeat an attack. However, this can lead to performance degradation. In this paper, we propose cache logical associativity. By combining this approach with CEASER-S, our cache, CEASER-SH, sacrifices less performance while maintaining the same security level against more advanced contention-based side-channel attacks. For example, compared with CEASER-S, CEASER-SH with a logical associativity of 3 can reduce the miss rate degradation by about 30% and that of the CPI by 1% while maintaining the same security level against a strong Prime+Probe attack.","PeriodicalId":142196,"journal":{"name":"2022 17th Conference on Ph.D Research in Microelectronics and Electronics (PRIME)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115014281","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 chip is being developed in a 65 nm CMOS technology and it is optimised for space applications. In each channel, the current pulse delivered by the sensor is amplified, converted into a voltage and sampled at 200 MS/s by an array of 256 cells, each containing a storage capacitor and a single-slope ADC. If a trigger signal is received, the analog samples are digitised in parallel and sent off-chip, otherwise the memory cells are overwritten. The ADC resolution can be programmed in the 7-12 bit range, trading-off dead time with amplitude resolution. The target power consumption is 5 mW/channel. The chip can thus take snapshots of relatively rare events at high sampling rate with low power. The analog memory can be partitioned in shorter slots that work in a time-interleaved configuration. In this way, the input data stream, which usually follows a Poisson distribution, can be derandomized. The chip is scheduled to be submitted for fabrication in the second quarter of 2022. In the paper, the design concept is presented and the ongoing verifications are discussed.","PeriodicalId":142196,"journal":{"name":"2022 17th Conference on Ph.D Research in Microelectronics and Electronics (PRIME)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134625692","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 OTA operates with a 0. 3V supply voltage and shows remarkable bandwidth performance with very limited power consumption, owing to the use of current mirrors with gain. Low impedance internal nodes of the current mirrors allow to boost gain and bandwidth, adding only high-frequency poles to the frequency response. Therefore, the compensation of the proposed OTA can be achieved through a dominant pole at the output, as in conventional cascode amplifiers. The circuit employs two identical input stages with cross-coupled inputs to improve common-mode rejection ratio (CMRR) performance, and a differential-to-single-ended output stage. The resulting architecture achieves a remarkable FOMs value, as demonstrated by the simulations performed in a commercial 130nm CMOS technology.","PeriodicalId":142196,"journal":{"name":"2022 17th Conference on Ph.D Research in Microelectronics and Electronics (PRIME)","volume":"142 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116398554","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 main disadvantages of chopping is the degradation of input impedance and the presence of chopping ripples superposing the recorded neural signal. These ripples are especially critical in sampled systems, as back-folding into the baseband should be avoided. Additionally, loop linearity and stability can be compromised by chopping ripples in feedback systems. This article compares ripple reduction strategies from prior art and presents a mathematical analysis of a simple and effective technique by delayed sampling. A description of the signal chain is derived in order to develop a model, which is subsequently used to demonstrate the effectiveness of the presented method. System-level simulations verify the functionality and yield a 30 dB ripple reduction at virtually no additional hardware expense.","PeriodicalId":142196,"journal":{"name":"2022 17th Conference on Ph.D Research in Microelectronics and Electronics (PRIME)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122234372","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}
