  1. 1. Development of an embedded system platform for signal analysis and processing

    University essay from Uppsala universitet/Signaler och system

    Author : Philip Lind; [2023]
    Keywords : Digital signal processing; DSP; digital filter; FIR; IIR; Butterworth; Chebychev; windowed sinc; Digital signalbehandling; DSP; digitalt filter; FIR; IIR; Butterworth; Chebychev; sinc; fönstermetoder;

    Abstract : Information is often stored and transmitted through electrical signals. This information may need refinement, which may be done by processing and altering the electrical signals, in which it is transmitted. When refining a signal, a frequency selective filter is often used. It can be implemented through digital signal processing (DSP). READ MORE

    Keywords : Radio Frequency energy harvesting; Antenna as a sensor; Long-Term Evolution; Rectifier; Printed Circuit Board; Altium Designer; Matching network; Voltage multiplier; Schottky diodes; Multiband LTE antenna; Ambient energy harvesting; Low power Internet of Things; Wireless power transfer; Radiofrekvensenergiskörd; Antenn som sensor; LTE; Likriktare; Printed Circuit Board; Altium Designer; Matchande nätverk; Spänningsmultiplikator; Schottky-dioder; Multiband LTE-antenn; Omgivande energiskörd; Lågeffekt Internet of Things; Trådlös kraftöverföring;

    Abstract : This thesis primarily deals with the concept of designing an antenna based device to harvest energy from Radio Frequency (RF) and using the harvested energy to sense the available Long Term Evolution (LTE) network in order for the Internet of Things (IoT) devices to connect to the network for the purpose of transmitting and receiving data. Secondarily the importance of this project is targeting how to conserve battery power in an IoT device and extend it’s lifetime. READ MORE

  4. 3. System Model of an Ultra-LowPower Fluorescence Detection Micro-Device

    University essay from Linköpings universitet/Elektroniska Kretsar och System

    Author : Yuanyuan Xue; [2020]
    Keywords : ;

    Abstract : This thesis aims to explore the power consumption limits of Complementary Metal-Oxide-Semiconductor (CMOS) fluorescent biosensors that meet the demand, a Matlab-based calculator is designed, in which users can input required system parameters (such as LED power and noise) to observe the minimum power consumption of each basic component and the constraints of the transimpedance amplifier: cut-off frequency, signal- to-noise ratio, dynamic range, etc. Thereby to provide a reference range for the next level designs of each component in the detection system.

  5. 4. Design and Implementation of a 2-Channel High Precision and High Speed Digitizing system

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Albert Llimós Muntal; [2016]
    Keywords : Analog; Digital; ADC; Digitizing; data acquisition; two channel; precision; resolution; speed; Technology and Engineering;

    Abstract : Recently, new spectroscopic techniques have been developed such as photocurrent detected two-dimensional spectroscopy [1], which measure the response from a sample that is excited by a high intensity laser pulses. The responses are linear and nonlinear signals that have very different amplitudes; the linear signal can be from 103 to 105 times larger than the nonlinear signal. READ MORE

  6. 5. Distortion Cancellation in Time Interleaved ADCs

    University essay from Linköpings universitet/Elektroniska Kretsar och System

    Author : Naga Thejus Sambasivan Mruthyunjaya; [2015]
    Keywords : Time-Interleaved ADC; Post correction; Blind calibration; Harmonics cancellation; Mismatch analysis; Linearisation;

    Abstract : Time-Interleaved Analog to Digital Converters (TI ADC) consist of several individual sub-converters operating at a lower sampling rate, working in parallel, and in a circular loop. Thereby, they are increasing the sampling rate without compromising on the resolution during conversion, at high sampling rates. READ MORE
