Abstract
An integrated circuit (1) has an array of single photon avalanche diodes (SPADS), a plurality of read-out circuits, each SPADS being coupled to one read-out circuit, wherein at least some of the read-out circuits comprise time-to-digital converters (TDC) and/or a digital asynchronous counter. The plurality of SPADS are coupled to one single read-out circuit. The read-out circuit may have a transformer for decoupling the SPAD from other parts of the read-out circuit.
