Description
120f サーミスタ
120g VCC
120h 信号グランド
120i 信号出力(+)
120j 信号出力(−)
120k 信号グランド
120l 内部接続
120m APDバイアス
両端の電極120f、120mが他の電極120g〜120lから離されているのは、サーミスタの出力電圧を高精度で検知するためである。APDバイアス回路はサーミスタの出力電圧よりも非常に大きな電圧信号が流れる。また、二つの信号出力ライン、120j、120k、には高周波信号が流れる。これら信号線、バイアス線からサーミスタの搭載位置を離すことにより、サーミスタからの信号線に雑音が重畳されるのを回避することができる。二つの信号出力、120i、120jはプリアンプの相補的な出力であり、所定の伝送インピーダンスを有するFPC基板上の配線120b、120cに接続されている。ここで、FPC基板上配線の伝送インピーダンスは、FPC基板の厚さ、材質(すなわちその材料の有する誘電率)、配線の幅、および配線金属の厚さにより決定される。そして、Gbpsを超える高速の信号をこの配線上に伝播させる場合には、配線の伝送インピーダンスを主回路基板上に搭載されている電子回路の特性インピーダンス(入力インピーダンス、出力インピーダンス)に整合させるのが、信号品質を保つ上で好ましい。10Gbpsを超える伝送速度の場合には、インピーダンス整合は必須となる。
