Abstract
Methods and systems for replicating high bandwidth current outputs from a photodetector or another current source include using a transimpedance amplifier (TIA) to directly generate a TIA voltage that is linear with optical power at the photodetector. The TIA voltage is used to generate a current that flows to a log amp, which generates a voltage that is linear with the optical power in dB. Additionally, offset cancellation is used at the TIA and at the log amp.
