Abstract
A medical device including an optical sensor is configured to measure an optical signal by integrating a current induced on a light detector of the optical sensor to obtain a voltage signal. The voltage signal is compared to a threshold. Responsive to the voltage signal reaching the threshold, an optical sensor control parameter is adjusted. The optical sensor is operated to produce the voltage signal using the adjusted control parameter.
