3. Prototyping and bringing the MHU into service
Wide application scope of MHU: phase advance prediction, phase shifting, phase correction, beam simulation, deterministic bunch-to-bucket filling, , bunch length measurement, optical transmission.
Status: concept worked out, detailed implementation has to follow.
Previous page: red tasks „finished“ until E/2017
Missing: implementation of „yellow“ parts,
interfacing, software/algorithms, bringing into service …

4. Precision high-speed clock phase adjustment
Outcome of a soon-to-be-ended DFG project:
Mixed-signal ASIC for clock adjustment
Clock sync. / Precise phase generation
Key properties
Clock signals in the GHz range
More than 6 bit phase resolution (~ 2.5fs)
Targetted for ASICs: can be made rad-hard
Phase-to-Digital Converter (PDC)
Scalable all-digital architecture
High-resolution (limited only by jitter)
Robust (no calibration needed)
Proposal:
Adaption/extension to accelerator requirements
Possible in rad-hard implementation (all digital, SOI-ASIC, redundancy concepts possible)

5. High-Voltage Generation and Application in ASICs
Novel trend in Integrated Electronics: fully integratable high voltage elements (transistors/capacitors) + „classical“ analog/digital transistors
High-Voltage := 700 V, silicon area of this transistor only 0,25µm2
„Classical“ electronics on same chip for precision control
Actual use cases
Applications which require multiple (miniaturized)
complex high voltage waveforms
E.g. pulse-width modulated, low power signals for sensors, antennas, ultra-sonic applications, electro-active polymers
Research directions
Stacking of transistors to even higher voltages (1200V / 1500V)
Combination with stacked MEMS for contacting „environment“
Of any use for accelerator community?
