Question about Avalanche Photodiode (APD)

[koopi]

Hi everyone,

How can I reach the breakdown voltage without applying the voltage written in the datasheet (80 volts!) , can I build a simple amplifier circuit with a battery of 5 V?
I wonder because every regular range meter with APD has a battery of 3 volts, so how do they reaching the brakdown voltage??



thank you!

To take advantage from the APD characteristic, a DC/DC converter will be needed.
