- It is worthwhile to notice that the minimum noise figure increases dramatically after hard oxide breakdown (HBD).It can be explained by the additional shot noise source in gate oxide after HBD. 值得注意的是金氧半场效电晶体在氧化层崩溃后会在氧化层区产生额外的散粒杂讯,因此其最小杂讯值会剧烈地增加。
- If the photodiodes have large amounts of dark current, much of the diode's signal capacity will be filled up by charge with no signal information. 如果光电二极管有大量的暗电流，大部分二极管信号电容会在没有信号情况下被充满。
- Etching the surface of germanium layer could decrease the dark current and increase the responsivity under the visible light exposure. 当蚀刻锗层的表面时，我们可以得到较低的暗电流并且提升可见光下的光响应。
