Assignee: MAXIM INTEGRATED PRODUCTS, INC.
Field: Basic communication processes (Electrical engineering)
Classification: CPC H | IPC H

Claim 9:
10. A system for increasing power efficiency in communication systems, the system comprising:
a signal processor that, at an interface, receives a digital signal that comprises a characteristic, the signal processor performing steps comprising:
determining whether the characteristic exceeds a threshold corresponding to an increase in a power requirement of a device;
in response to determining that the characteristic no longer exceeds the threshold, causing a driver circuit that is coupled to the signal processor to decrease a power output to conserve energy; and
encoding at least some of the digital signal with a control information that indicates that the characteristic exceeds the threshold to generate an encoded signal, the driver circuit comprising a controller that, in response to receiving the encoded signal, performs steps comprising:
extracting the control information; and
using the control information to generate a control signal; and

an amplifier circuit coupled to the driver circuit, the amplifier circuit, in response to receiving the control signal increases the power output to accommodate the increase in the power requirement of the device.
