Zusammenfassung:	Aspects of this disclosure relate to compensating for dynamic error vector magnitude. A compensation circuit can generate a compensation signal based at least partly on an amount of time that an amplifier, such as a power amplifier, is turned off between successive transmission bursts of the amplifier. For example, the compensation circuit can charge a capacitor based at least partly on an amount of time that the amplifier is turned off between successive transmission bursts and generate the compensation signal based at least partly on an amount of charge stored on the capacitor. A bias circuit can receive the compensation signal, generate a bias signal based at least partly on the compensation signal, and provide the bias signal to the amplifier to bias the amplifier.
