Photocurrent monitor circuit and optical receiver |
摘要 |
<p>Since this photocurrent monitor circuit can detect, by way of first and second current mirror circuits 2F, 2R, a current proportional to the photocurrent flowing into a photodiode 1 from a photocurrent monitor terminal IMT, it can monitor the correct photocurrent without its detecting circuit influencing the photocurrent of the photodiode itself. <IMAGE></p> |
