Abstract
The present disclosure relates generally to methods and materials for detecting light released from a labeling material using self triggering excitation. In particular, the present disclosure provides an architecture for a detection system that detects accumulated phase shifts in the form of a ring-oscillator frequency. The present disclosure provides devices for detection of a light released by a labeling material, the device comprising: a start-up circuit that provides power to a pulse generator block that drives an LED driver, a photodetector that detects the light released by a labeling material and provides a first signal; a variable reference that provides a second signal; a slicer for comparing the first signal to the second signal, wherein the slicer generates an output signal with a delay that triggers the pulse generator block after the start-up circuit is disabled; a frequency reference; and a frequency counter for comparing the output from the slicer to the frequency reference thereby producing a output signal.
