Inverse function method for semiconductor mixer linearity enhancement |
摘要 |
The mixer circuit includes a differential rf input driver; a differential local oscillator input circuit coupled to the differential rf input driver; a non-linear load coupled to the differential local oscillator input circuit wherein the non-linear load compensates for non-linearity of the differential rf input driver. The non-linear load has a V-I (voltage-current) transfer function the inverse of the input driver. This improves the mixer linearity without sacrificing the Gain or Noise Figure.
