We present a high precision Time-to-Digital Converter (TDC) architecture suitable for multi-channel implementations in monolithic arrays of single-photon avalanche diode (SPAD) detectors aimed at TCSPC applications (like FLIM, FCS, FRET), but also at photon timing and direct TOF measurements for 3D ranging applications (e.g. in LIDAR systems). A “smart-pixel” with a SPAD detector, an analog sensing...
This paper presents the design of a low-noise multi-channel front-end readout chip integrated with a high-resolution TDC. It is foreseen to be used as front-end readout electronics of Avalanche Photo Diodes (APD) dedicated to a small animal Positron Emission Tomography (PET) system. The architecture of the chip is depicted. Two prototype chips, a ten-channel front-end chip and a three-channel high-resolution...
This paper presents a fast lock all-digital delay-locked loop (ADDLL) with a wide range and high resolution all-digital duty cycle corrector (ADDCC), which achieves low jitter, fast lock time, and accurate 50% duty cycle correction with a clock-synchronized delay (CSD) and time-to-digital converter (TDC) schemes. The ADDLL uses a self-calibration scheme to reduce the phase error and jitter, and a...
