dc.description.abstract | The design and measurements of a CMOS 64 × 64 Single-Photon Avalanche-Diode (SPAD) array with in-pixel
Time-to-Digital Converter (TDC) are presented. This paper thoroughly describes the imager at architectural and circuit
level with particular emphasis on the characterization of the SPAD-detector ensemble. It is aimed to 2D imaging and 3D
image reconstruction in low light environments. It has been fabricated in a standard 0.18μm CMOS process, i. e. without
high voltage or low noise features. In these circumstances, we are facing a high number of dark counts and low photon
detection efficiency. Several techniques have been applied to ensure proper functionality, namely: i) time-gated SPAD
front-end with fast active-quenching/recharge circuit featuring tunable dead-time, ii) reverse start-stop scheme, iii)
programmable time resolution of the TDC based on a novel pseudo-differential voltage controlled ring oscillator with
fast start-up, iv) a global calibration scheme against temperature and process variation. Measurements results of
individual SPAD-TDC ensemble jitter, array uniformity and time resolution programmability are also provided. | es |
