Direct current (DC) correction circuit for a time of flight (TOF) photodiode front end

摘要: A system and method that compensates for the effects of ambient light in a time flight (TOF) sensor front end is provided. Moreover, direct current (DC) correction loop utilized at end, which removes DC component from generated by TOF accordingly prevents saturating end. The attenuates without adding significant thermal noise modulation frequency provides corrected signal to circuitry. processed detect position an object within optical field sensor.
