Abstract: Time-correlated single-photon counting (TCSPC) 3D imaging requires the digitization of photon arrival times across an array of single-photon avalanche diodes (SPADs). The most critical performance metrics of time-to-digital converters (TDC) in TCSPC applications are their… read more here.

Abstract: This article presents an area- and power-efficient transmission/receiving (TX/RX)-isolation switch implemented in a 3072-ch ultrasound (US) in-probe 2-D array transceiver application-specific integrated circuit (ASIC) for real-time 3-D imaging. Conventional T/R switches that protect low voltage… read more here.
