Proceedings International Conference on Next Generation Communication and Information Processing Incip 2025, 2025
Among all factors considered in the design of VLSI, the issue of power consumption is a very critical point, especially for memory elements like DRAM. This work develops the FSPA-VLSA, Foot Switch PMOS Access Voltage Latch Type Sense Amplifier which saves considerable power - 84% - while reading DRAM cells. The possibility of open bit architecture makes it relevant for low-power designs in VLSI and ULSI technologies. The circuit has been designed and implemented using Cadence Virtuoso tools at a 45nm technology node, thus demonstrating its effectiveness in contemporary electronic applications. - IOT Based Smart Syringe Infusion and IV Fluid Monitoring and Alerting System

One therapeutic device that mechanically injects medication directly into a patient's body at a predetermined dose and time in millilitres per hour is a syringe pump. The delivery of fluids, including vitamins and capsules, directly into a patient's body in a controlled setting is one of the most important requirements of a treatment that requires special attention. In recent years, health care has become increasingly focused on technology. Today's technology is expected to be useful and simple to use. It is now easier to use clinical devices wirelessly for tele-monitoring and telemedicine over long distances because to developments in Wi-Fi and the Internet of Things (IoT). To improve fitness care in rural areas, a low-cost clinical syringe pump framework is developed on this picture. The purpose of this study is to design a syringe pump that can be operated remotely by medical professionals, such as nurses or doctors, using a NodeMCU V3 WiFi module. A dc motor-pushed syringe pump is assembled using a microcontroller board that contains crucial motive force circuits. The armature voltage of the DC motor is adjusted to produce remarkable drift rates. At the feed screw, the gear converts the motor's spin into linear movement. There are several options for Wi-Fi tool control, protection measures, and drift charge controls. - Air Quality Beacon Using Internet of Things

Air pollution is getting worse every day in both wealthy and developing nations, lowering the air quality index and harming everyone. A few of the factors contributing to this sharp rise in air pollution are the expanding population, an increase in industry, the speed at which cities are urbanizing, and the overuse of fuel-intensive modes of transportation. Therefore, the need for energy-efficient, pervasive, and networked air quality monitoring is only growing. This paper presents the architecture, functionality, and outcomes of our Air-MIT air quality monitoring device, which fills and uploads data securely to the cloud server over the Internet of Things (IoT). Our low-cost Internet of Things (IoT) air monitoring system can detect several dangerous gases and particulates in the air, including carbon dioxide (CO2), methane gas (CH4), carbon monoxide (CO), and ammonium (NH4). Additional sensors may be added to the system to further enhance its detection capabilities. Real-time indoor air quality monitoring is built into the system, and if any of the readings exceed the pre-established threshold, an alarm will sound. In order to prevent accidents or fires, the gadget also has the ability to activate the exhaust fan in the kitchen or house to ventilate the area and remove any toxic gas exposure. - Analysis of crosstalk noise in coupled MWCNT interconnects using MRTD technique

In this paper, the crosstalks induced effects are explored in mutually coupled multi-walled carbon nanotubes (MWCNTs) interconnect lines driven by CMOS gates. The crosstalk delays and the peak voltages on the victim line for functional and dynamic crosstalk are investigated. The analyzes has been done for multiwalled carbon nanotubes and copper on-chip interconnects for 22nm technology node. The results show that exploiting the MWCNT interconnects instead of Cu leads to 61.35% shorter functional crosstalk delay, 12.80% lower functional crosstalk voltage and 59.14% lower dynamic in-phase crosstalk delay and 67.38% lower dynamic out-phase crosstalk delay. For different load capacitances utilizing the MWCNT interconnects instead of Cu leads to 62.79% shorter functional crosstalk delay, 63.54% lower dynamic in-phase crosstalk delay and 68.24% lower dynamic out-phase crosstalk delay. The simulation results show that the MWCNT is significantly highly efficient than conventional copper (Cu) on-chip interconnects. It is observed the results shows that the MWCNT are more fit for very large-scale integration system as compared to the Cu. - Transient Analysis of Crosstalk Noise Effects in SWCNT Bundle On-Chip Interconnects Using MRTD Technique

Carbon nanotube bundles are being considered as a potential on-chip interconnect replacement for conventional copper on-chip interconnects in the nanoscale regime of recent IC technology. This paper analyzes the signal integrity analysis of CMOS gate-driven single-walled carbon nanotubes (SWCNTs) bundle on-chip interconnects. The wavelet-based numerical model Multiresolution Time Domain (MRTD) method is used for the transient analysis of SWCNTs bundles on-chip interconnects. The proposed MRTD model is used to perform transient analysis for parameters of signal integrity, peak crosstalk, and propagation delay estimations. The obtained results of the proposed MRTD model are compared with those of the conventional Finite Difference Time Domains (FDTD) model and it is validated with SPICE simulator at 32 nm technology node and also compared with multiwalled CNT (MWCNT) interconnects at 22 nm. The MRTD model results show excellent agreements to SPICE with less than 0.41% error. The elapsed CPU runtimes for the MRTD model are significantly less compared to SPICE. The MRTD model is used to interconnects the model with two and three lines and can be extended to an M-coupled line. The results of the proposed model are closely matched to those of SPICE simulations. - Thyroid Diagnosis Using Multilayer Perceptron

In high-speed regime, as the PCBs (Printed Circuit Boards) are diminished, and the continuous increasing of the clock frequency in the state-of-the-art digital systems, at higher frequencies there is no more interconnects are transparent. The behavior of the electrical properties of traces (Transmission lines) plays a major role in determining the performance of the PCB board. As an enormous increase of frequencies and usage of data rates and decreasing of size, it's necessary to check the signal integrity issues on a PCBs to reduce failure products. In this paper, we design and analyzed the coupled transmission lines for a single-ended micro-strip model with $50\\Omega$ characteristic impedance and extracted RLC parameters. Estimated the Near End Crosstalk(NEXT) and Far End Crosstalk (FEXT) noise in ADS and validated with SPICE Tool on victim line and also, compared with an empirical equations values. - Modeling of capacitive coupled interconnects for crosstalk analysis in high speed VLSI circuits

In this paper, we estimated the crosstalk noise for CMOS driver with capacitive coupled interconnect model in High-speed digital VLSI circuits. Crosstalk noise is one of the essential parameters for designing accurate interconnect models. As monotonically increasing of clock frequencies, circuit density and decreasing of rise time, degrading the circuit performance.
