PROJECT TITLE :
Small area 0.3 pJ/conv, 45 ps time-to-digital converter for arrays of silicon photomultiplier interfaces in 150 nm CMOS
A ring-oscillator-based mostly time-to-digital converter (TDC) is presented that can achieve a figure-of-advantage of zero.3 pJ/conv in an exceedingly terribly little footprint of 0.0024 mm2. Due to the optimisation of the ring-oscillator and of the sub-cycle interpolation, a 45-ps LSB is obtained with only zero.95 mW of power consumption. The realm and power characteristics build the TDC appropriate for its use in repeated instances, like in multiple silicon photomultipliers readout channels or single-photon imaging devices with time-correlated detection.
