The PDD ASIC: highly efficient energy and timing extraction for high-rate applications

The peak detector derandomizer ASIC provides threshold discrimination, arbitration, peak and timing detection with analog memory, sparsification, and multiplexing for 32 input channels of analog pulse data. In this work the ASIC is characterized for high-rate operation. A new version of the ASIC, can process multiple events occurring at the same time and provides time-over-threshold measurement for pile up rejection.
