  1. 1. Simulation and Construction of a Half-Bridge Class D Audio Amplifier

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Johan Engstrand; Niklas Kavathatzopoulos; Jonathan Nordenholm; [2018]
    Keywords : amplifier; class D; half-bridge; simulation; LTspice; KiCad; förstärkare; klass D; halvbrygga;

    Abstract : Usage of class D audio amplifiers has become increasingly widespread in recent years, mainly due to their high efficiency, which can reach almost 100 %. Class D amplifiers can also be compact, making them suitable for mobile applications. In contrast, the most efficient conventional amplifiers such as class B can reach a maximum efficiency of 78.

  2. 2. Design of an Optimal Analogue Microphone System for Best Possible Capture of Incoming Acoustic Signals

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

    Author : Johan Sunnanväder; [2016]
    Keywords : Analogue Analog Microphone System Sound Audio Capture Acoustic Signals Electronics; Technology and Engineering;

    Abstract : This project examines how to achieve the best possible capture of incoming acoustic signals in a surveillance camera without overspending. This will be done by designing a complete analogue microphone system to be integrated into a surveillance camera and identify the critical stages in terms of performance. READ MORE

  3. 3. Understanding the Parasitic Effects on the Microwave Interferences at Hearing Instrument Level up to 6GHz

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

    Author : Thomas Sofya; [2016]
    Keywords : Technology and Engineering;

    Abstract : The use of electronic devices which radiate high power electromagnetic waves has seen a significant increase in the last 20 years. These radiated signals heavily effects electronic devices close to strong radio frequency (RF) or microwave (MW) transmitters . READ MORE

  4. 4. System Analysis and Implementation of Delta-Sigma Modulator Topologies with Low Gain Amplifiers in 90nm CMOS

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Bilal Shahzad; [2011]
    Keywords : ;

    Abstract : Data converters are one of the key components in many applications ranging from wireless communication to data acquisitions system, sensors, audio electronics, video display electronics and analog microcontrollers. All of these use some type of data converter to perform the task of signal processing/condition for example in RF transceivers the received analog signal after passing through filters is converted to digital signal for further processing.

  5. 5. Audio power amplifier design

    University essay from Avdelningen för elektronik, matematik och naturvetenskap

    Author : JINGJIE SUN; YINGJUN CHEN; [2011]
    Keywords : audio power amplifier;

    Abstract : The audio power amplifier is used to amplify low-power audio signals to a level that can be suitable for driving the loudspeakers. Thus the audio power amplifier becomes a kind of essential part in the electronics that could make sounds. In this thesis, a good performance audio power amplifier with tonality control is designed.
