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： An integrated circuit for a radio receiver comprising a radio-frequency amplifier and a radio-frequency filter is described. The amplifier receives radio-frequency signals from an antenna, the filter is connected to the amplifier output, and the output of the filter is provided to a processing stage of the receiver. The amplifier comprises an amplifying stage controlled by a radio-frequency input signal and a signal fed back from the filter. The amplifier input impedance is substantially matched to the antenna impedance at a frequency band of interest. The signal fed back from the filter providing attenuation of signals outside the frequency band of interest at the amplifier input. The filter comprises one or more filter components. A filter component comprises a first input and a second input for receiving the amplifier output, a first switch arranged to selectively connect the first input to a first impedance, a second switch arranged to selectively connect the first input to a second impedance, a third switch arranged to selectively connect the second input to the first impedance, and a fourth switch arranged to selectively connect the second input to the second impedance. The first and fourth switches are controlled by a first oscillator signal and the second and third switches are controlled by a second oscillator signal that is 180° out of phase with the first oscillator signal.

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： A transconductor circuit includes a first input device M1 and a second input device M2 each having a control terminal coupled to a radio frequency input signal, and a bias setting device MB having a control terminal coupled to the radio frequency input signal and an output coupled to the control terminal of each of said M1 and M2. MB is partitioned into two equal sized bias setting devices MB1 and MB2. In the preferred embodiment MB1 and MB2 are coupled to the control terminals of M1 and M2 for establishing a bias voltage at the control terminals of M1 and M2. The circuit is shown to substantially cancel second-order intermodulation distortion and to enhance a second order intercept point.

摘要： A resonant load circuit is disposed in an integrated circuit, where the resonant load circuit includes an integrated inductance in parallel with an integrated capacitance, and further includes a first integrated resistance Rs in series with one of the inductance and capacitance, preferably in series with the inductance, and a second integrated resistance Rp in parallel with the inductance and capacitance. The first and second integrated resistances have values selected for reducing an amount of resonant load circuit Q over a plurality of instances of the integrated circuit. In a preferred, but non-limiting, embodiment the resonant load circuit forms a load in an RF low noise amplifier, such as a balanced inductively degenerated common source low noise amplifier (LNA).
