We define partial cognitive relay channel as a two-transmitter, two-receiver interference channel with a relay node such that one of the transmitters is a cognitive transmitter. As a more feasible assumption we assume that the cognitive transmitter has non ...
On board of satellites traditionally Travelling Wave Tube Amplifiers (TWTAs) together with standard waveguide technology were used for transmitters in telecommunication payload systems. With the advent of Solid State Power Amplifiers (SSPAs) printed circui ...
Today's world of electronics becomes more and more digital and therefore CMOS becomes the dominant technology. A CMOS process compared to a bipolar process offers several advantages, mainly a low power consumption which is important for portable systems po ...
This thesis aims at developing wireless systems with a strong emphasis on low-power consumption and low-voltage operation. The main technical objective is the development of a single cells battery operated fully integrated CMOS RF transceiver that fulfills ...
Theoretical and experimental work on the vertical position control system on the COMPASS-D tokamak is described. An analog proportional + derivative (P + D) system is currently used, and two important sources of disturbance are observed in the system. One ...
Wireless communications are showing an explosive growth in emerging consumer and military applications of radiofrequency (RF), microwave, and millimeter-wave circuits and systems. Applications include wireless personal connectivity (Bluetooth), wireless lo ...
A Hall sensor comprises a Hall element (1; 30; 31; 60) and an amplifier (2; 32; 33). The Hall element is placed inside the amplifier so that the current flowing through the Hall element also flows through the transistors of an amplifier stage of the amplif ...
The differential pair is one of the basic amplifying stages in amplifier design. Aiming at the the design of low-distortion amplifiers, a simple model for a differential pair is derived using the Volterra series. The parameters in this model correspond to ...
Boltzmann electron energy distribution poses a fundamental limit to lowering the energy dissipation of conventional MOS devices, a minimum increase of the gate voltage, i.e. 60 mV, is required for a 10-fold increase in drain-to-source current at 300 K. Neg ...
In this paper we present a method for predicting nonlinear distortion in electronic circuits using the Volterra series. Simple expressions for the distortion in a Common-Emitter stage are determined. Designers may use these expressions to get a quick insig ...
