A 128-channel event-driven ASIC is described which reads out the R3B (Reactions with Relativistic Radioactive Beams) silicon micro vertex tracker. Ionizing particles with energies in the range of 40keV-50MeV are detected, digitized and read out with 12 bit resolution, and time stamped with up to 5ns precision. The ASIC copes with signal charges and detector leakage currents of both polarities and...
This manuscript introduces a transistor level technique that results in simultaneous improved slew rate and noise performance for applications where only the final settled output voltage over a predefined time frame is important — such as silicon detector read out charge-to-voltage reset amplifiers. For large signal swings, slew limitation is detected and compensated dynamically. For non-slew limiting...
