Abstract: A system and method are disclosed for decreasing the amount of power consumed by a wireless signal receiver in a wireless device. Received data is communicated from the receiver to a play-out buffer in communication with a media play-out device. The level of data in the play-out buffer increases when received data is written to the buffer, and the level of data decreases when data is read from the buffer. If the level of data is above a first watermark level, the receiver is transitioned to a sleep mode while data is read from the buffer. When the level of data in the buffer falls below a second watermark level, the receiver is transitioned back to an active mode to receive data. The device communicates status messages (whether the receiver is asleep or active) to the transmitting device so that the transmitting device stops transmitting data when the receiver is in sleep mode, and transmits data when the receiver is in the active mode.

Abstract: The method and apparatus disclosed herein reduces the power consumption of a wireless transceiver by reducing the power consumption associated with the corresponding wireless receiver. Generally, a power mode selection unit enables or disables a low power mode based on a dynamic range requirement for the receiver.

When enabled, the negative resistance compensates for the gain lost by lowering the transconductance of the RF front-end amplifier, which enables the front-end gain associated with the low-power mode to be maintained relative front-end gain associated with the normal mode.
