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. More particularly, when the dynamic range requirement is less than or equal to a threshold, the power mode selection unit lowers the transconductance of an RF front-end amplifier in the receiver and enables a negative resistance at an output of the RF front-end amplifier. 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.
