Abstract
There is proposed an optical power measurement circuit and an optical power meter which use a linear amplification circuit based on multiple transimpedance operational amplification lanes and which add a bootstrap circuit and a compensator circuit. 1) The bootstrap is used to reduce the effect of the photodiode capacitance and increases the amplifier's bandwidth. 2) The compensator circuit monitors the photodiode's voltage and reproduces its transient distortions, to then subtract it from the output and thereby reduce the measurement error.
