Voltage level diagram of LOFIC-CMOS image sensors used to reduce input-referred noise and to increase pixel FWC. (a) HCG signal: gain of double sampling circuit should be high to decrease the input referred noise at FD node; (b) LCG signal: gain in double-sampling circuit should be low to increase the signal swing at FD node.
