Abstract
Techniques for time-based measurements using photodetectors are disclosed. In one particular embodiment, the techniques may be realized as a system for determining a physiological parameter comprising one or more photodetector systems configured to receive light from a light source and including a front-end circuit and a photodetector and time-to-digital converter circuitry configured to receive a sensing signal from the front-end circuit and output a triggering time for determining the physiological parameter.
Claims20
A system for determining a physiological parameter, the system comprising:
- one or more photodetector systems configured to receive light from a light source and including a front-end circuit and a photodetector;
- and
- time-to-digital converter circuitry configured to receive a sensing signal from the front-end circuit and output a triggering time for determining the physiological parameter.
A method of controlling one or more photodetector systems to determine a physiological parameter, the method comprising the steps of:
- receiving light provided by a light source at the one or more photodetector systems, the one or more photodetector systems including a front-end circuit and a photodetector that receives the light;
- producing a sensing signal from the front-end circuit based on the photodetector receiving the light;
- and
- receiving the sensing signal by time-to-digital converter circuitry that outputs a triggering time for determining the physiological parameter.
One or more non-transitory computer-readable media storing executable instructions that, when executed by one or more processors, determine a physiological parameter using one or more photodetector systems by:
- receiving light provided by a light source at the one or more photodetector systems, the one or more photodetector systems including a front-end circuit and a photodetector that receives the light;
- producing a sensing signal from the front-end circuit based on the photodetector receiving the light;
- and
- receiving the sensing signal by time-to-digital converter circuitry that outputs a triggering time for determining the physiological parameter.
