| 摘 要： | 本文从理论上分析了并联电感和串联电感对ＰＩＮ－ＦＥＴ前瑞的作用，证明谐振电感可以有效地抑制ＦＥＴ热噪声的影响，在１．０～１．５ＧＨｚ频率范围内得到接近由量子散粒噪声决定的极限灵敏度。在实验上制作了ＧＨｚ级高速光接收机前端，并用微波网络分析仪测试了前端的频率响应。测试结果与理论分析基本相符。

| Abstract: | In this paper we analyse the action of paralled and serial resonant inductor on PIN-FET frontend,proving that the influence of FET thermal noise can be greatly decreased and that the utmost sensitivity relying on shot noise may be obtained between 1.0 and 1.5GHz.We experimentally fabricate GHz high speed optical receiver front-end and measure their frequence response using microwave network analyzer.The test result is in accordance with the theory. |

| Keywords: | Optical receiver front-end shot noise thermal noise resonant inductor. |
