Abstract
An envelope tracking device includes a fine slot peak tracking (FSPT) circuit, at least one power amplifier, and an envelope modulator. The FSPT circuit is connected to the power amplifier through the envelope modulator. The FSPT circuit generates envelope signals based on input signals, adds an offset to the envelope signals, and expands and smoothes the added envelope signals. The envelope modulator generates envelope voltage signals according to the smoothed envelope signals, and outputs the signals to drain of the power amplifier. The envelope voltage signals are time-aligned with the amplified signals which are transmitted to gate of the power amplifier.
