However, attempts to realize the RPU concept based on non-volatile memory technology face a myriad of technological and physical constraints. The theoretical concept of crossbar array is nearly impossible to implement in the real world without certain tweaks. Hence, we propose an Voltage output Complementary Metal Oxide Semiconductor (CMOS)-based RPU design VRPU, which is used to build a neural network. We also introduce a novel diode-based circuit to behave as a non-linear activation function, which consists of a single Diode (D) and Diode Pair (DP). The proposed VRPU design when tested with MNIST dataset for hidden layer and output layer combinations of ReLU+Sigmoid, D+Sigmoid, ReLU+DP, D+DP (low temperature) and D+DP (high temperature) resulted in accuracies of 94.29%, 95.90%, 95.53%, 96.75% and 96.57% respectively corroborating the merits of the proposed design.","PeriodicalId":6792,"journal":{"name":"2021 IEEE International Midwest Symposium on Circuits and Systems (MWSCAS)","volume":"1 1","pages":"59-62"},"PeriodicalIF":0.0,"publicationDate":"2021-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79892718","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}

Nonlinear activation introducing the non-linearity in the learning process is one of the critical building blocks of artificial neural networks. Hyperbolic tangent and sigmoid are the most commonly used nonlinear activation functions in machine-learning system such as neural networks. This work demonstrates the stochastic computation of tanh(ax) and sigmoid(2ax) functions-based Bernstein polynomial using a bipolar format. The format conversion from bipolar to unipolar format is involved in our implementation. One achievement is that our proposed implementation is more accurate than the state-of-the-arts including FSM based method, JK-FF and general unipolar division. On average, 90% of improvement of this work in terms of mean square error (MAE) has been achieved while the hardware cost and power consumption are comparable to the previous approaches.","PeriodicalId":6792,"journal":{"name":"2021 IEEE International Midwest Symposium on Circuits and Systems (MWSCAS)","volume":"17 1","pages":"386-390"},"PeriodicalIF":0.0,"publicationDate":"2021-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87022244","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 ME antenna design of this work is under development for wireless communication with implantable devices, where one role of the antenna is to receive pulse-modulated power from a nearby transmitter. In this application, the proposed behavioral ME antenna model can be utilized during design optimizations of the energy harvesting circuits. The model has been assessed through simulations with an energy harvester design in 65nm CMOS technology.

A current generator circuit is used to generate a supply independent current to bias the active load in the temperature compensation circuit. Drain-source voltage of two critical MOSFETs is made equal in the current generator circuit by using a feedback arrangement to ensure a high PSRR of -75dB for the reference voltage. Temperature compensation is achieved by using the complementary to absolute temperature (CTAT) nature of gatesource of a MOSFET operating in the subthreshold region and proportional to absolute temperature (PTAT) nature of conventional composite pair architecture. The proposed CVR is designed in TSMC 180nm technology. The circuit works desirably for a supply range of 0.85V to 2.3V while generating a reference voltage of around 0.68V. Maximum temperature coefficient (TC) of 184 ppm/°C and minimum TC of 69 ppm/°C are noted for mismatch and process variations in the Monte-Carlo simulation for 1000 samples. The circuit consumes only 46nW of power, which makes it suitable for ultra-low power applications.","PeriodicalId":6792,"journal":{"name":"2021 IEEE International Midwest Symposium on Circuits and Systems (MWSCAS)","volume":"24 1","pages":"995-998"},"PeriodicalIF":0.0,"publicationDate":"2021-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86296926","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}

Applications of wireless ranging and localization include home and automotive access systems, indoor ranging, asset tracking, proximity sensing, distance estimation, gaming, security perimeter enforcement, and relay attack prevention to name a few. Unlike wide-band systems, NBW systems consume much lower power for each transmission and reception making them suitable for battery powered applications and possess wireless range that is an order of magnitude higher than wideband systems, allowing them to meet the requirements for several line-of-sight (LOS) and non-line-of-sight (NLOS) application conditions.
