ABSTRACT:
A physiological sensor includes a light source in optical communication with a light detector. A controller is in communication with the light detector via a connector. A booster circuit is in communication with the light detector and the connector. The booster circuit may be configured to buffer signals generated by the light detector and reduce an input capacitance on either the controller or terminals of the connector. In various embodiments, the booster circuit may be disposed on the connector for a reusable cable or a disposable sensor pad.
