The reference signal driving the photodiode has a fixed amplitude, while the amplitude of the measured signal changes with the amount of light reflected.
A high speed InGaAs PIN photodiode is integrated with a transimpedance preamplifier and bypass chip capacitors, and is encapsulated in a small TO-46 package.
フォトダイオードのスペクトル応答の波長依存度が高いことは、メリットにもデメリットにもなり得ます。
The highly wavelength-dependent spectral response of photodiodes can be both an advantage and a drawback.
The attenuation of the light intensity, caused by absorption by dissolved substances andundissolved material is detected by a hermetically sealed photodiode.
Digital output detectors which are combined both photo diodes and signal processing circuits(amplifier, Schumitt Trigger, voltage regulator) in one-chip.
フォトダイオードの種類によっては、負荷抵抗が応答速度に影響を与える場合があります。
Depending on the type of the photodiode, load resistance can affect the response speed.
さらに、入力オフセット電圧が小さければ、フォトダイオードの暗電流が最小限に抑えられます。
In addition,a small input offset voltage will minimize the photodiode's dark current.
バイアス電圧がゼロでない限り、フォトダイオードの出力もゼロにはなりません。
The output of the photodiode is nonzero as long as the bias voltage is nonzero.
