Abstract
A method for power management in an electronic circuit that comprises a processing system and an RF embedded circuit includes: generating a first regulated voltage with a power regulation module of the RF embedded circuit; generating a second regulated voltage from the first regulated voltage with a first linear regulator of the processing system; and controlling the power regulation module of the RF embedded circuit to operate according to a plurality of operation modes. The operation modes include: a first sleep mode in which a switched-mode power supply of the RF embedded circuit is off and a second linear regulator of the RF embedded circuit is off; a second sleep mode in which a switched-mode power supply is off and the second linear regulator is on; and a third sleep mode in which the switched-mode power supply is on and the second linear regulator is off.
