Gary Varner Design Choices • Input coupling – Differential versus single-ended input – Needed analog bandwidth – Gain needed? • Sampling Options – On‐chip PLL/DLL – External DLL – Analog transfer vs interrogate in situ • ADC and readout options • ADC and readout options – Sequential output select vs random access – On‐chip vs. off‐chip ADC – Serial, parallel, massively parallel
Gary Varner Constraints - Analog Bandwidth - Switching noise - Leakage current - Deeper sampling Extensive radio array for UHE neutrinos - Super B Factory PID Upgrade – precision timing
