Abstract
A single-pixel photon counter is designed using a folded cascode CMOS operational amplifier which is self-biased. Since there is no need for a voltage bias circuit, the layout area and power consumption of the designed counter are reduced. The signal voltage of the designed charge sensitive amplifier (CSA) with the MagnaChip
본 논문에서는 자체 바이어스가 되는 Folded Cascode CMOS OP Amp를 이용하여 싱글 픽셀 포톤 계수기 회로를 설계하였다. 전압 바이어스 회로가 필요 없으므로 싱글 픽셀의 레이아웃 면적을 줄이고 전류 소모를 줄일 수 있다. 매그나칩 반도체
