A high speed/high linearity continuous-time delta-sigma modulator
Dissertation
(Universität Ulm, 2017-12-01)
Modern wireless communication systems demand wideband ADCs with high resolution and high linearity. Among different ADC topologies, CT Delta Sigma modulators are very popular due to inherent anti-aliasing filtering and ...
Pulse modulation techniques for switched-mode transmitter
Dissertation
(Universität Ulm, 2016-04-25)
Nowadays more and more communication devices incorporate multiple transceivers operating in different frequency bands. To reduce form factor and power consumption of such devices, a fully digital, multi-standard, multiband ...
Concept and design of a high speed current mode based SAR ADC
Dissertation
(Universität Ulm, 2016-07-20)
There is continuous research to exploit the improved speed of scaled CMOS technologies in realizing high-speed analog-to-digital converters and SAR ADCs are one of the candidates which can significantly benefit from this ...
