   Abstract : The main purpose of this work is to study methods to simulate electro-thermal effects in integrated circuits using CONCISE a waveform relaxation based circuit simulator. WR is a method that is suitable to run on a multi-computer with state of the art computing power. Especially CMOS VLSI circuits have been simulated successfully with WR. READ MORE

4. 2. Linear Transmitter Design Using Nonlinear Analog Circuits

   Author : Bo Shi; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication engineering; Elektronik och elektroteknik; Electronics and Electrical technology; BiCMOS.; CMOS; ASIC; Radio-frequency circuits; Translinear circuits; RF power amplifier linearization; Linear transmitter; Nonlinear analog circuits; Telekommunikationsteknik;

   Abstract : This dissertation deals with analog techniques at both the architecture and circuit design levels for designing power efficient linear radio-frequency (RF) transmitters. The use of nonlinear analog integrated circuits to implement certain critical signal processing functions for the multiplicative feedback and LINC techniques is investigated with the aim of improving the system performance in terms of complexity, linearity and power efficiency.

5. 3. Reduction of Substrate Noise in Mixed-Signal Circuits

   Author : Erik Backenius; Mark Vesterbacka; Kejll O. Jeppson; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mixed-signal; Substrate noise; Substrate modeling; Simultaneous switching noise; SSN; Digital; Analog; Clock; Electronics; Elektronik;

   Abstract : In many consumer products, e.g., cellular phones and handheld computers, both digital and analog circuits are required. Nowadays, it is possible to implement a large subsystem or even a complete system, that earlier required several chips, on a single chip. READ MORE

6. 4. Nanowire Transistors and RF Circuits for Low-Power Applications

   Author : Karl-Magnus Persson; Institutionen för elektro- och informationsteknik; []
   Keywords : InAs; Nanowire; Metal-oxide-semiconductor field-effect transistor; MOSFET; RF; Mixer; Circuit; 1 f-noise; Simulation; Modelling;

   Abstract : The background of this thesis is related to the steadily increasing demand of higher bandwidth and lower power consumption for transmitting data. The work aims at demonstrating how new types of structures, at the nanoscale, combined with what is referred to as exotic materials, can help benefit in electronics by lowering the consumed power, possibly by an order of magnitude, compared to the industry standard, silicon (Si), used today.
