Description
但し、Ccopはコプレナー線路の全容量値であり、Lcopはコプレナー線路の全インダクタンス値である。この数式(1)からも明らかなように、部分的インピータンスZは容量Cbcにも依存するため、部分的インピータンスZを50Ω等の設計値に近づけるためには、コプレナー線路単体のインピーダンスを50Ω以上とし、且つ容量Cbcを含めて50Ωに近づくようなインダクタンスLcpを確保することが必要となる。そして、そのためにはコプレナー線路に十分な線路長が必要となる。
但し、Routは駆動回路の出力インピーダンスであり、RLは光変調器のインピーダンスである。また、記号「//」は、2つの抵抗が並列接続されたときの合成抵抗値を表す。
図10は、上記実施形態の第1変形例に係る駆動回路10Bの構成を示す回路図である。この駆動回路10Bは、次に説明する点を除いて、上記実施形態に係る駆動回路10Aと同じ構成を備えている。
図15は、上記実施形態の第2変形例に係る駆動回路10Cの構成を示す回路図である。この駆動回路10Cは、次に説明する点を除いて、上記第1変形例に係る駆動回路10Bと同じ構成を備えている。
