摘要： 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.

摘要： The method and apparatus described herein address problems associated with conventional wireless receivers configured for intra-band carrier aggregation. The disclosed solution applies the received signal to a single front-end amplifier, which may comprise a low-noise amplifier, and divides the amplified signal into two or more processing paths, where each path is associated with a different local oscillator frequency corresponding to a different reception band. To compensate for the impact of the additional processing paths on the amplifier performance, a negative resistor unit applies a negative resistance to the output of the front-end amplifier when two or more processing paths are active.

摘要： The present invention relates to a method and circuit arrangement for adjusting a gain, wherein said circuit arrangement comprises at least a first output branch connected to a first load and a second output branch connected to a second load. The gain control function is realized based on a current splitting, wherein a non-operated output branch is used as a kind of dummy branch for receiving a part of the output current. Thus, only as many output branches as there are outputs are required to implement a gain control based on splitting. Thereby, a complexity of the layout design is reduced and control and biasing of dummy branches is not required.

摘要： Disclosed is a multi-mode radio frequency amplifier. The amplifier includes a plurality of input transistors, a plurality of output branches, and a switching stage interposed between the plurality of input transistors and the plurality of output branches for selectively connecting the plurality of input transistors to the plurality of output branches. Individual ones of operational modes of the multi-mode amplifier correspond to an individual one of the plurality of frequency selective loads. A particular one of the plurality of frequency selective loads is one of operating or non-operating during operation of the multi-mode amplifier. A gain of the multi-mode amplifier is reduced by controlling the plurality of elements to steer a predetermined portion of a total signal current that is output from one of the input transistors, from an associated operating frequency selective load to a non-operating frequency selective load.
