Abstract
A fast-switching power management integrated circuit (PMIC) is provided. The PMIC is configured to provide an average power tracking (APT) voltage to a power amplifier circuit for amplifying a radio frequency (RF) signal modulated in multiple time intervals. Herein, the PMIC is configured to increase or decrease the APT voltage from a present voltage level in a present one of the time intervals to a future voltage level in an upcoming one of the time intervals with very short switching interval (e.g., <20 nanoseconds). When the APT voltage transitions from the present voltage level to the future voltage level, the PMIC opportunistically activates a voltage amplifier to help ensure proper operation of the power amplifier circuit (e.g., maintain the APT voltage at the present level and reduce ripple in the APT voltage). As a result, the PMIC can switch the APT voltage frequently and rapidly with reduced inrush current.
