Memristor based neural networks (MNN) address the speed and energy efficiency issues in computing hardware. However, there are still a lot of problems with memristor, and the limited size of memristor crossbar resulting in the accuracy of the MNN is lower than conventional neural networks (CNNs). In this paper, a modified Dropout and Maxout based MNN for improving the accuracy of the MNN is proposed. A three-layer memristor based multilayer Perceptron (MLP) in 64*128 crossbar is built to perform MNIST image recognition. The experiment results demonstrate that the in-situ training of the MLP achieves a high accuracy near 96.5% with Dropout and Maxout.","PeriodicalId":6727,"journal":{"name":"2020 IEEE 15th International Conference on Solid-State & Integrated Circuit Technology (ICSICT)","volume":"46 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2020-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90544575","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}

Besides, cascade current mirror was also used for improving power supply rejection ratio (PSRR). This wideband TIA was designed in standard 0.35 CMOS technology. Simulation results show that the proposed TIA has a bandwidth of 145 MHz, low frequency transimpedance gain of 93 $mathrm{dB}Omega$, phase margin of more than 66° and low frequency power supply rejection ratio (PSRR) of $-157dB$. And the average input referred noise current spectral density is 6. $8mathrm{pA}/sqrt{mathrm{H}mathrm{Z}}$ from DC to 500 MHz.

A low-input impedance current buffer employing current feedback is developed to achieve direct charge integration without the use of power-hungry charge-sensitive amplifiers (CSAs). A customized 10-bit SAR ADC is designed for energy digitization. The ADC is shared among 16 readout channels to reduce the chip area and improve power efficiency. The SAR ADC reuses the charge integration capacitor in each readout channel as the ADC sampling capacitor to further lower the power consumption. To reduce the SiPM noise-induced timing measurement error, an on-chip high-pass filter (HPF) based fast pulse generation approach is developed to sharpen the long-tailed SiPM current pulses into fast pulses. With a 1.8 V power supply, the SAR ADC consumes 743 µW at 16 MS/s, and achieves a SNDR of 56.48 dB and a SFDR of 62.53 dB. The on-chip fast pulse generation brings a 35 ps improvement in timing resolution without increasing the number of I/O pin counts. Including the front-end current buffer, current mirrors, charge integrator and the shared ADC, each channel of the readout system consumes 3.8 mW of power with a conversion period of 1 µs.","PeriodicalId":6727,"journal":{"name":"2020 IEEE 15th International Conference on Solid-State & Integrated Circuit Technology (ICSICT)","volume":"36 6 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2020-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78012234","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}
