CHARGE PUMP FOR LOW POWER CONSUMPTION APPARATUS AND ASSOCIATED METHODS

摘要

An apparatus includes a first set of circuits adapted to operate in a first mode of operation of the apparatus. The apparatus further includes a second set of circuits adapted to operate in a second mode of operation of the apparatus, where a power consumption of the apparatus is lower in the second mode of operation of the apparatus than in the first mode of operation of the apparatus. The apparatus also includes a charge pump adapted to convert a first supply voltage of the apparatus to a second supply voltage, and the second supply voltage powers the second set of circuits.

主权项

1. An apparatus having first and second modes of operation, comprising:
a first set of circuits that operate in the first mode of operation of the apparatus; a second set of circuits that operate in the second mode of operation of the apparatus; a charge pump coupled to receive a first supply voltage and to convert the first supply voltage to a second supply voltage; and a switch to selectably supply power to the second set of circuits by coupling either the first supply voltage or the second voltage to the second set of circuits such that a power consumption of the apparatus is lower in the second mode of operation of the apparatus than in the first mode of operation of the apparatus.
