| IP개요 | We describe a low power, small area time-to-digital converter (TDC) based on Venier cyclic digital controlled oscillator (DCO) structure. The TDC is designed to be combined with an array of single photon avalanche diodes (SPAD) arranged in a digital silicon photomultiplier (SiPM) architecture to form a fluorescence lifetime sensor. The high dynamic range is achieved by using two individual counter in two continuous conversion steps: coarse step and fine step. The third step quantifies the time residue to achieve high resolution. |
