Abstract

we present a fully digital single-chip solution to fluorescence lifetime
sensing implementing lifetime estimation on-chip using the centre-of-mass
method. A time-multiplexed, multichannel TDC architecture is introduced
to allow the pile-up limit to be broken, achieving a maximum
100Mphoton/s acquisition rate, whilst still allowing lifetime decays of common
organic fluorophores to be obtained. The device comprises a 1.3×1.7mm2 CMOS
chip in 0.13μm technology, featuring an array of SPAD detectors in a silicon photomultiplier
architecture, the multichannel TDC architecture, a CMM processing
block and a serial interface for control and data capture.
