Contrary to popular belief, the human red-sensitive opsin's peak response is not in the red region of the visual spectrum; its peak sensitivity is 560 nm, which corresponds to a " yellowish-green " color, i . e . between green ( 530 nm ) and yellow ( 580 nm ).
12.
For the same bias conditions and device type, this circuit exhibits flat frequency response to 50 MHz, has a peak response less than 0.7 dB \ scriptstyle \ left ( \ left | H _ { WCM } \ left ( s \ right ) \ right | ~ = ~ 1.08 \ right ) at 160 MHz and falls below its low-frequency response at 350 MHz.
