  1. 16. 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.

    Abstract : Radio Astronomers demand for highly sensitive astronomical facility. Their demand is a radio telescope that can detect the weakest and deepest radio signal. To fulfill the demand of high sensitive telescope, an entirely new way of realizing a radio telescope is required. READ MORE

  5. 19. Modeling of RF-design at board level for Assisted Global Positioning System (AGPS)

    University essay from Institutionen för teknik och naturvetenskap; Tekniska högskolan

    Author : Michael Paszowski; [2007]
    Keywords : ;

    Abstract : This thesis describes the design of a 1575.42 MHz Low-Noise Amplifier (LNA) using a Hetero-Junction Field Effect Transistor (HJ-FET) from NEC. The LNA design focuses on a minimum noise figure and good power gain in order to improve receiver sensitivity. READ MORE

  6. 20. Current Distribution in High RF Power Transistors

    University essay from Ämnesavdelningen för elektronik

    Author : Jihad EL-Rashid; Youssef Tawk; [2007]
    Keywords : Current Distribution in High RF Power Transistors;

    Abstract : To obtain the power levels required from high RF power transistors, the size of the chip has often to be made so large that inductance of electrical connections inside the package cannot be neglected. This may have the effect that various parts of the transistor chip are not connected exactly parallel, i.e. READ MORE
