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.
