Abstract
A multi-mode power management circuit is provided. The multi-mode power management circuit includes a second generation (2G) amplifier circuit(s) configured to amplify a 2G radio frequency (RF) signal for transmission in a 2G RF band(s). The multi-mode power management circuit includes a pair of tracker circuitries coupled to the 2G amplifier circuit. Each tracker circuitry includes a charge pump circuitry configured to generate a voltage and a current. When the 2G amplifier circuit amplifies the 2G RF signal for transmission in the 2G RF band(s), both charge pump circuitries are controlled to provide two currents to the 2G amplifier circuit. As a result, the 2G amplifier circuit is able to amplify the 2G RF signal to a higher power corresponding to a sum of the two currents for transmission in the 2G RF band(s).
