1. 16 GS/s Continuous-Time ΣΔ Modulator in a 22 nm SOI Process : a Simulation and Feasibility Study
University essay from Linköpings universitet/Tekniska fakulteten; Linköpings universitet/Elektroniska Kretsar och SystemAbstract : With a reference specification model in terms of 8 GS/s Sigma Delta Modulator in a 28 nm CMOS process consuming 890 mW, the purpose with this thesis is to construct a similar and simpler model but with higher specification demands. In a 22 nm SOI process with an input signal bandwidth of 500 MHz sampled at 16 GS/s with a power consumption below 2 W, the objective is to design a Continuous-Time Sigma Delta Modulator with verified simulated functionality on a transistor level basis.

3. Design and Simulation of Miscellaneous Blocks of an All-Digital PLL for the 60 GHz Band
University essay from Elektroniksystem; Tekniska högskolanAbstract : A phase-locked loop commonly known as PLL is widely used in communication systems. A PLL is used in radio, telecommunications, modulation and demodulation. It can be used for clock generation, clock recovery from data signals, clock distribution and as a frequency synthesizer. Most electronic circuits encounter the problem of the clock skew. READ MORE

5. High-Speed Hybrid Current mode Sigma-Delta Modulator
University essay from Elektroniksystem; Tekniska högskolanAbstract : The majority of signals, that need to be processed, are analog, which are continuous and can take an infinite number of values at any time instant. Precision of the analog signals are limited due to influence of distortion which leads to the use of digital signals for better performance and cost. READ MORE
