Patent attributes
A multi-mode mobile power management circuit is provided. The multi-mode mobile power management circuit includes a dual-mode amplifier circuit(s) configured to amplify a radio frequency (RF) signal for transmission in a defined RF band(s), such as a long-term evolution (LTE) band(s) or a fifth-generation new radio (5G-NR) band(s). The multi-mode mobile power management circuit includes a pair of tracker circuitries coupled to the dual-mode amplifier circuit. Each tracker circuitry includes a charge pump circuitry configured to generate a voltage and a current. When the dual-mode amplifier circuit amplifies the RF signal for transmission in the 5G-NR band(s), both charge pump circuitries are controlled to provide two currents to the dual-mode amplifier circuit. As a result, the dual-mode amplifier circuit is able to amplify the RF signal to a higher power corresponding to a sum of the two currents for transmission in the 5G-NR band(s).
