An optical signal detector monitoring circuit can include a current divider current mirror (CDCM) and a current multiplier current mirror (CMCM). A mirror leg of the CDCM generates a current corresponding with a part of the CDCM's primary leg current. The CMCM's primary leg couples to the CDCM's mirror leg. The CMCM generates a mirror leg current corresponding with a multiple of its primary leg current. Another circuit can include a first current mirror having a primary current leg (PCL), coupled between an optical signal detector and one of an electrical source and an electrical sink, that exhibits a resistance corresponding with a part of the resistance of the first current mirror's mirror current leg (MCL). The circuit's second current mirror has a MCL that exhibits a resistance corresnonding with a part of the resistance of the second current mirror's PCL, which couples with the first current mirror's MCL.
