Abstract
Methods, systems, and devices for voltage control for wireless devices are described. The described techniques may enable a wearable device to dynamically select and adjust the starting input voltage (e.g., VLED) for one or more light emitting diodes (LEDs). In particular, a wearable device may dynamically determine the starting input voltage of the LEDs based on an LED configuration to be used by the LEDs, and a threshold anode line voltage to power the LEDs. The LED configuration may include parameters or characteristics of the LEDs to perform physiological measurements.…
