The designs are based on stacked low-voltage standard CMOS transistors. The different pre-input stage circuits are compared to each other in terms of their circuit description, drawbacks, advantages and simulation results. The principle of the five designed pre-input stage circuits can be applied to higher voltage range input signals as well.}, language = {en} } @inproceedings{KonetzkeRutschHoffmannetal., author = {Konetzke, Eric and Rutsch, Matthias and Hoffmann, Maik and Unger, Alexander and Golinske, Ren{\´e} and Killat, Dirk and Ramadas, Sivaram Nishal and Dixon, Steve and Kupnik, Mario}, title = {Phased array transducer for emitting 40-kHz air-coupled ultrasound without grating lobes}, series = {Proceedings, IEEE International Ultrasonics Symposium (IUS), 21 Oct - 24 Oct 2015}, booktitle = {Proceedings, IEEE International Ultrasonics Symposium (IUS), 21 Oct - 24 Oct 2015}, publisher = {IEEE}, doi = {10.1109/ULTSYM.2015.0019}, pages = {4}, language = {en} } @inproceedings{PashminehKillat, author = {Pashmineh, Sara and Killat, Dirk}, title = {Self-biasing high-voltage driver based on standard CMOS with an adapted level shifter for a wide range of supply voltages}, series = {IEEE, Nordic Circuits and Systems Conference (NORCAS), NORCHIP \& International Symposium on System-on-Chip (SoC), Oslo, Norway 2015}, booktitle = {IEEE, Nordic Circuits and Systems Conference (NORCAS), NORCHIP \& International Symposium on System-on-Chip (SoC), Oslo, Norway 2015}, publisher = {IEEE}, address = {Piscataway, NJ}, doi = {10.1109/NORCHIP.2015.7364405}, pages = {1 -- 4}, language = {en} } @inproceedings{PashminehKillat, author = {Pashmineh, Sara and Killat, Dirk}, title = {Design of High-Voltage Level Shifters Based on Stacked Standard Transistors for a Wide Range of Supply Voltages}, series = {SBCCI'15, Proceedings of the 28th Symposium on Integrated Circuits and Systems Design}, booktitle = {SBCCI'15, Proceedings of the 28th Symposium on Integrated Circuits and Systems Design}, publisher = {ACM}, address = {New York, NY}, isbn = {978-1-4503-3763-2}, doi = {10.1145/2800986.2801003}, pages = {6}, language = {en} } @misc{PashminehKillat, author = {Pashmineh, Sara and Killat, Dirk}, title = {High-voltage circuits for power management on 65 nm CMOS}, series = {Advances in Radio Science}, journal = {Advances in Radio Science}, number = {13}, doi = {10.5194/ars-13-109-2015}, pages = {109 -- 120}, abstract = {This paper presents two high-voltage circuits used in power management, a switching driver for buck converter with optimized on-resistance and a low dropout (LDO) voltage regulator with 2-stacked pMOS pass devices.
