Miniature low-noise photodiode system |
摘要 |
A miniature low-noise photodiode amplifier system that minimizes offset and drift has the output of a photodiode connected to the non-inverting input of an operational amplifier. The operational amplifier has a split voltage supply and the output of the operational amplifier is transmitted to a rectifying diode. A second amplifier to increase the output of the operational amplifier is not required when this miniature low-noise photodiode amplifier system is employed.
