Method and apparatus of an input resistance of a passive mixer to broaden the input matching bandwidth of a common source/gate LNA |
| 摘要 |
A cascode amplifier circuit comprises a first spiral inductor coupled to a source of a first transistor; a second spiral inductor coupled to a drain of a second transistor; a third inductor connecting the first transistor to the second transistor; a first capacitor coupled in parallel to the third inductor forming a bandpass filter; and a second capacitor coupled in parallel to the second spiral inductor forming a resonant circuit, wherein the resonant circuit oscillates at a center frequency. |
