Inductive powering for a mobile communication device and a radio frequency integrated circuit

摘要

A power status signal is received in an integrated circuit that indicates an inductive power status of an inductive power module and a power status of an alternative source. A power mode is selected based on the at least one power status signal. A power mode signal is generated based on the selected power mode. A power supply signal is generated and adjusted in response to the power mode signal.

主权项

1. A communication device comprising:
a radio frequency integrated circuit (RFIC) that generates a power mode signal based on a selected one of a plurality of power modes, the RFIC including a RF transceiver circuit and a baseband processing circuit; an inductive power circuit that generates an inductive power signal from a remote reader; a power management circuit, coupled to the RFIC and the inductive power circuit and at least one alternative power source, wherein the power management circuit:
receives the power mode signal;generates a power supply signal from one of, the inductive power signal and the at least one alternative power source; andselectively implements one of a plurality of power conservation measures of the communication device based on commands indicated by the power mode signal.
