Variable gain constant bandwidth trans-impedance amplifier for fiber optic rate sensor |
摘要 |
A trans-impedance amplifier with gain control for a fiber optic rotation rate sensor. A variable gain amplifier having gain control based on keeping the amplifier output above a certain level. The gain control approach allows the amplifier bandwidth to remain constant. A gain control circuit includes a control device connected to ground and the amplifier feedback network. The input to the gain control circuit may be the amplifier output that has been filtered, or the input could be from an external circuit or microcontroller. |
