Abstract

Reducing equivalent series resistance (ESR) of a power management circuit during single transmission is disclosed. The power management circuit includes multiple power amplifier circuits each configured to amplify a signal for transmission. The power management circuit includes a main multi-level charge pump (MCP), a first voltage modulation circuit, a lightweight MCP, and a second voltage modulation circuit. When only one of the power amplifiers is active to amplify the signal for single transmission, the power management circuit will opportunistically couple the main MCP, the first voltage modulation circuit, the lightweight MCP, and the second voltage modulation circuit to the active power amplifier. As such, the active power amplifier will see a reduced ESR that is collectively presented by the main MCP, the first voltage modulation circuit, the lightweight MCP, and the second voltage modulation circuit, and can thus operate with improved efficiency during the single transmission.
