 技術摘要 / Our Technology： |
本發明有關於一種低雜訊疊接放大器,主要包括有一第一電晶體、一第二電晶體、一第三電晶體、一第一電感及一第二電感,其中第一電晶體透過第一電感而與第二電晶體相連接,第二電晶體則透過第二電感與第三電晶體相連接,並形成一疊接電路,使用在高頻的時候電感會與電晶體所產生的雜散電容產生共振,藉此將可有效降低疊接放大器在高頻時所產生的雜訊。
The present invention relates to a low noise cascode amplifier comprising a first transistor, a second transistor, a third transistor, a first inductor, and a second inductor. Furthermore, the first transistor can connect with the second transistor via the first inductor, and the second transistor can connect with the third transistor via the second inductor; thereby, a cascode device can be formed. The inductor and the parasitic capacitances can resonate at high frequency, so that the noise figure of the cascode amplifier can be reduced.
