    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.
