Abstract

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.

First claim

What is claimed is:

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 sourc…
