Abstract
Aspects of an envelope tracking operation are described. In some aspects, as part of the envelope tracking operation, a device determines a change in a first set of power amplifier (PA) operating conditions, corresponding to a first look up table (LUT), the first LUT defined by a first LUT equation and a maximum supply voltage value. In some aspects, the device autonomously generates a second LUT equation to define a second LUT, having a second set of corresponding PA operating conditions. In some aspects, the device selects values from the first LUT equation, estimates a slope of the second LUT equation, determines an intercept with a maximum power value, and adjusts a supply voltage input for the PA to a supply voltage according to the maximum power value.
