“…LAB4 switched-capacitor arrays [6] are used for digitization due to their their high sampling rate (2.6 GSa/s) and low power requirements. However, this comes at the cost of slow readout and complicated calibration for the analog buffers.…”

Abstract.The ANtarctic Impulsive Transient Antenna (ANITA) collaboration deploys balloonborne interferometric antenna payloads that fly at 37 km above Antarctica. The primary goal is detection of Askaryan emission from cosmogenic neutrinos interacting in the Antarctic ice. In addition, ANITA has proven sensitive to radio signals from extended air showers. Here, we provide a review of the results of previous missions, with a special focus on recent results, and a preview of our upcoming mission.

“…These devices have been used as low-power substitutes for flash ADCs for the past 25 years; some of the most representative examples are described in references [12][13][14][15][16][17][18][19]. SCA channels are the basic building blocks of the presented ASIC architecture, so a general descrip-120 tion is included here first.…”

The new TRacking Array for light Charged particle Ejectiles (TRACE) detector system requires monitorization and sampling of all pulses in a large number of channels with very strict space and power consumption restrictions for the front-end electronics and cabling. Its readout system is to be based on analog memory ASICs with 64 channels each that sample a 1 µs window of the waveform of any valid pulses at 200 MHz while discarding any other signals and are read out at 50 MHz with external ADC digitization. For this purpose, a new, compact analog memory architecture is described that allows pulse capture with zero dead time in any channel while vastly reducing the total number of storage cells, particularly for large amounts of input channels. This is accomplished by partitioning the typical Switched Capacitor Array structure into two pipelined, asymmetric stages and introducing FIFO queue-like control circuitry for captured data, achieving total independence between the capture and readout operations.

“…In the end, one simply cannot do better than having a high-fidelity "oscilloscope on a chip" for every sensor channel. Cost and data volume precluded this type of waveform recording until recent generations of SCA ASICs [26,27,28,29,30] demonstrated such techniques were practical, especially for large systems.…”

Recent advances in photon detectors have resulted in high-density imaging arrays that offer many performance and cost advantages. In particular, the excellent transit time spread of certain devices show promise to provide tangible benefits in applications such as Positron Emission Tomography (PET). Meanwhile, high-density, highperformance readout techniques have not kept on pace for exploiting these developments.Photodetector readout for next generation high event rate particle identification and time-resolved PET requires a highly-integrated, low-power, and cost-effective readout technique. We propose fast waveform sampling as a method that meets these criteria and demonstrate that sub-10ps resolution can be obtained for an existing device. BackgroundRecent developments in high-density, high precision timing photodetectors are finding applications in Cherenkov detection techniques for particle identification, as well as medical imaging applications. This is true for both traditional vacuum-based [1] (Micro-Channel Plate, Hybrid Photo-Diode) and solid state [2] (Geiger-mode APD) photodetectors, and have resulted in lower cost, higher quantum efficiency, and improved transit-time-spread (TTS) photon detection options. Fig. 1 illustrates that without these improvements, the performance of large-scale Time-OfFlight (TOF) systems for precision spectrometers has stagnated at a resolution of about 100ps. * Corresponding author.
