This paper intends to lay the groundwork for detection of backlash nonlinearity in a two-mass rotational system representing a vehicle driveline. It involves experiments and practical considerations prior to carrying out a system identification of the plant. Four possible system configurations are elaborated. Parameter estimation is then carried out in Dymola. Practical factors that affect the quality...
This paper will investigate the sensing delay optimization and power consumption of each sense amplifier. The optimization will apply multi-Vth or MTCMOS techniques for better sensing delay, with the critical path transistors will use low-Vth model. The initial optimization is done by calculating for the most proper transistor sizing in term of sensing delay and power. The result obtained shows MTCMOS...
This project describes the design of a Multi-sized Output Cache Controller that will handle 2Kbyte 16 ways with 4 word block size cache. A cache controller is a device that used to sequence the read and write of the cache storage array. Most of modern microprocessor is designed with multiple core architecture that will lead to massive traffic of cache data transfer. By taking the advantage of using...
This paper mainly discussed the process to classify Anthracnose and Downey Mildew, watermelon leaf diseases using neural network analysis. A few of infected leaf samples were collected and they were captured using a digital camera with specific calibration procedure under controlled environment. The classification on the watermelon's leaf diseases is based on color feature extraction from RGB color...
In this study, significant information of red flesh watermelon ripeness is determined by using a spectrometer and Statistical Package for the Social Science (SPSS). A few of red flesh watermelons were measured in both non-destructive and destructive method by using a spectrometer to identify the significant ripeness features in various grades. Visible light (VIS) and near-infrared (NIR) are used as...
This paper describes a comparative study of comparator and encoder in 4-bit Flash Analog to Digital Converter (ADC) for Pipeline ADC to obtain a high speed ADC. In this paper, the conventional comparator is replaced with an open loop comparator and the non-ROM type encoder is used as the alternative for the conventional encoder. It is implemented using 0.18μm CMOS technology. Generally, the Silvaco...
This project focuses on improving the performance of a plant's sludge dewatering process by using Omron CP1E Programmable Logic Controller (PLC) to increase the efficiency of the process which leads to a reduction in cost of the polymer product. The process requires manually mixing the cationic polymer long chains with raw water to produce a product that will be sent to the sludge tank process and...
This paper presents the comparison between multistage amplifier and folded cascode amplifier design using 0.18μm CMOS technology. The objective of this project is to compare gain and power dissipation between these two design models. Sample and hold circuit (SHC) is the main component in pipelined ADC. Designing a low power, high gain SHC is crucial, that is the main reason why multistage amplifier...
This paper discusses the design and analysis of a latching comparator using charge sharing circuit topology for low power and high speed. This topology combines the good features of the resistive dividing comparator and the differential current sensing comparator. This design will be focusing on the minimization of propagation delay and the power dissipation of the comparator, which will improves...
The fruit industry requires rapid, economical, and non destructive method for classifying fruits by internal quality. This research studied the development of a non destructive method that would enable consumers and producers to assess the maturity of papayas rapidly. Near Infra Red Spectroscopy (NIRS) was used to assess total Soluble Solid Content (SSC). A device consisting of infrared receiver sensor...
