1. Multiband LNA Design and RF-Sampling Front-Ends for Flexible Wireless Receivers
Sammanfattning : The wireless market is developing very fast today with a steadily increasing number of users all around the world. An increasing number of users and the constant need for higher and higher data rates have led to an increasing number of emerging wireless communication standards. LÄS MER
2. Sequential 3D Integration - Design Methodologies and Circuit Techniques
Sammanfattning : Sequential 3D (S3D) integration has been identified as a potential candidate for area efficient ICs. It entails the sequential processing of tiers of devices, one on top the other. LÄS MER
3. Active and Passive Unequally Spaced Reflect-Arrays and Elements of RF Integration Techniques
Sammanfattning : Using an array synthesis tool based on a modified differential evolution algorithm, it is shown that the position-phase synthesis exhibits improved pattern characteristics compared to both the phase only and position only synthesis of uniform amplitude antenna arrays. The design of an unequally spaced planar reflect-array and an active power combining reflect-array are presented. LÄS MER
4. Vertical Heterostructure III-V MOSFETs for CMOS, RF and Memory Applications
Sammanfattning : This thesis focuses mainly on the co-integration of vertical nanowiren-type InAs and p-type GaSb MOSFETs on Si (Paper I & II), whereMOVPE grown vertical InAs-GaSb heterostructure nanowires areused for realizing monolithically integrated and co-processed all-III-V CMOS.Utilizing a bottom-up approach based on MOVPE grown nanowires enablesdesign flexibilities, such as in-situ doping and heterostructure formation,which serves to reduce the amount of mask steps during fabrication.

5. Design and Characterization of RF-LDMOS Transistors and Si-on-SiC Hybrid Substrates
Sammanfattning : With increasing amount of user data and applications in wireless communication technology, demands are growing on performance and fabrication costs. One way to decrease cost is to integrate the building blocks in an RF system where digital blocks and high power amplifiers then are combined on one chip. LÄS MER
