Second order intermodulation reduction circuit in direct conversion receiver, controls second order intermodulation of mixer by detecting output voltage of mixer and by adjusting gain of common mode feedback circuit |
| 摘要 |
<p>A common mode feedback circuit (210) controls second order intermodulation of a mixer (200) by detecting output voltage of mixer and by adjusting gain of common mode feedback circuit. A load impedance (208) is connected between the output terminals (206) of the mixer. An independent claim is also included for direct conversion receiver.</p> |
